Answer:
A
Explanation:
It was dormant and is now active best describes the volcano. There are three types of volcanoes: active, dormant, and extinct. Thus, option A is correct.
Active volcanoes have recently erupted; they are likely to do so once more. Volcanoes that are dormant have not erupted in a very long time but could do so in the future. It seems unlikely that extinct volcanoes will erupt in the near future.
Thus, Magma, or molten rock, accumulates in a chamber inside an active volcano. The magma escapes onto the surface of the planet through channels in the rock as a result of pressure building up inside the magma chamber. Lava is the name given to magma once it spills onto the surface.
Thus, A is the ideal selection.

The number of protons in an atom is called the atom's________ . Each chemical element has a unique_________ . Most hydrogen atoms have only a single proton in their nucleus, so a hydrogen atom that also has one neutron is an_________ of hydrogen. An atom with more electrons than protons has a negative________ .isotopeatomic numberelectric chargeatomic mass number
Answer: Mass number, atomic number, atomic number, isotope, charge
Explanation:
The total sum of the protons and neutrons in the atomic nucleus is called mass number. It is approximately equal to the mass of the atom.
The number of protons that are present in the nucleus of an atom is called atomic number. It is represented by letter Z.
Each chemical element has a unique atomic number because of the presence of same type of atoms in an element.
The isotope is a variant of a particular chemical element. All isotopes have similar protons but different neutrons in numbers. Hydrogen can have different isotopes depending upon the number of neutrons.
An atom that have more electrons than protons will have a negative charge because electrons are responsible for imparting negative charge.

what is one benefit of privately issued student loans?
a. they are issued in cooperation with the students University to reduce cost and paperwork
B. they have lower interest rates and can be paid back with a lower out of pocket cost
C. they are backed by the US government to ensure greater Financial Security
D. they are available to any student who meets lending standards regardless of financial need
Answer:
D. They are available to any student who meets learning standards regardless of financial need.
Explanation:
Private student loan is an option for financing which is meant for higher studies from college or bank for student education. This type of loan is available to any student who meets learning standards but do not allow for income-driven repayment plans. There is also no student loan forgiveness. Credit check is required in this type of loan financing so as to know whether the student has loan elsewhere and whether he is up to date in terms of repayment.
Once the loan has been taken, one can start paying up but there is a grace period of six months within which repayment must be fully made. The loan can be refinanced, no borrowing rates, have variable interest rate, hence no interest ceiling.
Native species of North America are often defined as those species that were present in North America before Europeans arrived in the early 1600s. When Europeans arrived, they found extensive forests dominated by the American chestnut tree. These chestnut trees were extensively cultivated and planted by the North American natives for food and other wood products. In the early 1900s the chestnut blight (a fungus) virtually exterminated all of the American chestnut trees from North America.
(a) Is the American chestnut considered a native species despite its intensive cultivation? Explain why.
(b) Is the chestnut blight considered a native or invasive species? Explain why.
(c) Discuss why invasive species tend to proliferate at very high rates.
(d) Many people are trying to grow hybrid chestnut trees that will be immune to the chestnut blight so that forests can be restored to those found by the Europeans in the 1600s. Do you agree or disagree that this should be done? Justify your answer
Answer:
a) Yes! the American chestnut tree is a native species. The American chestnut tree was present before the Europeans arrived in North America in the 1600s. Since a native species has been defined as any species that was present in North America before the arrival of the Europeans, then it is a fact that the North American chestnut tree is a native species.
b) The chestnut blight is an invasive species that is native to east East Asia, and was accidentally introduced into North America around the early 1900s, when the Japanese chestnut was commercially cultivated in the United States.
c) Invasive species tend to proliferate at a very high rate because they lack some natural constraints in the new environment such as natural predators, competition, and as in the case of this chestnut blight; the host has no natural defense mechanism against them. These conditions allow them thrive more than they would in their natural environment, unchecked
d) Yes, I agree with this idea, albeit to some extent. The development of hybrid chestnut resistant to the chestnut blight will possibly return the forests back to how it was before the Europeans arrived in the 1600s, but the genetic conservation will be altered, since these new trees will be an hybrid of the old trees, and the forest won't truly be as it was before the 1600s

Trace fossils represent fossilized behavior and usually do not include any of the original organic material. Identify the trace fossils in the images by dragging the labels to the correct location.
a) footprints
b) feeding marks
c) burrows
d) coprolites
Answer:
1. d) coprolites, 2. b) feeding marks, 3. a) footprints, 4. c) burrows
Explanation:
Trace fossils are those that have a fossil record of the biological activity and not the preserved parts of the plants and are usually altered by the later chemical activity or mineralization. A coprolite is a fossilized feace and are opposed to the body fossils and is evident from the behaviour of the animals and formed in different shapes and compose of animal dung. The feeding marks are the longest and deepest tooth marks left by carnivorous dinosaurs. Burrows in a fossil is the remains of the holes and tunnels excavated into the ground or the seafloor. The footprints are the tracks that are left by the ancient animals upon the sedimentary rocks.Why mountains (any 2 )in uae differ in color

True
False
Answer:
True
Explanation:
The fourth methods outlined in the paragraph are useful to determine the nature of the differences between the geology of northern and southern Arizona.
This is because these geology differences can manifest in seismic profiles, in geologic history (for example, the differences in the rock formations that form the soil of the two regions), in drill core studies, and also, in a detailed map of the geology of the state, where ideally, the results from the previous studies would be mapped.

What were the first two great continents in continental drift
Pangea, the last supercontinent formed some 360 million years ago by the grouping of all existing continental masses, begins to separate 130 million later, during the transit between the Permian and Triassic, and it does so by fragmenting into two major continents:
One, which begins to drift north and is called Laurasia, and another, which drifts south, called Gondwana. These two great continental masses are separated by the Neotethys ocean.
Laurasia will subsequently fragment and give rise to what will be Eurasia and North America, while the rest of the continents will separate from Gondwana: South America, Africa, Antarctica and Indoaustralia, which in turn will break, giving rise to the Indian and Australian subcontinents.
It is 45°C at sea level. What will the temperature be at 5500 meters? Use the normal lapse rate.
Answer: 9.25°C
Explanation:
As you move higher from sea level, the temperature drops at an average rate. This average rate at which the temperature drops is known as the lapse rate.
This rate is 6.5 °C per 1000 m.
Temperature at 5,500m has dropped by;
= 6.5 * [tex]\frac{5,500}{1,000}[/tex]
= 35.75 °C
Temperature has decreased by 35.75 °C.
Temperature at 5,500m above sea level is;
= 45 - 35.75
= 9.25°C

1. Is there a relationship between the locations of earthquake epicenters, volcanoes, and plate boundaries? If so, describe the relationship. 2. According to the theory of continental drift, all of the world’s continents were once connected as one large landmass and have, over the course of hundreds of millions of years, drifted apart into the positions they occupy today. Do the results of this activity support the theory of continental drift? If so, how? Explain your answer. 3. Why is it easier to predict where an earthquake epicenter will occur than it is to predict when it will occur? Explain. 4. The Richter scale describes how much energy an earthquake releases. With every increase of 1.0 on the scale, 32 times more energy is released. How many times more energy would be released by a quake measuring 2.0 more units on the Richter scale? 5. Why do you think the area around the Pacific Plate is called the Pacific Ring of Fire? 6. The Hawaiian Islands have formed as the Pacific Plate moves northwestward over a hot spot of Earth’s interior that provides magma to form several volcanos. Explain what could happen if the Pacific Plate continues to move. 7. How can volcanic eruptions be predicted?
Answer:1Earthquakes occur along fault lines, which are all the types of plate boundaries.
Volcanoes are located along converging plate boundaries and diverging plate boundarie
2Yes. The reason that earthquakes and volcanoes occur is the plate moving. The magma rises and pushes the
both-side crust. That causes continents moving and volcanoes and earthquakes happen.
3Now people know earthquakes happen along the plate boundaries, so they can predict where it is going to
happening. However, they cannot know when it happens. People cannot predict when the plates are going
to move.
4 64 time more
5There is the area that volcanoes and earthquakes happen usually.6
6Those formed islands are going to keep moving northwesrward and the magma from the hotspot will rise,
cool, and form a new island.
7Before an eruption, magma will rise toward the surface and break the rocks. That causes the hotter surface
and an earthquake. For these two reasons, people can predict volcano eruptions.
Essay 1.Why rural settlements have declined 2.reasons why city dwellers opt for the country 3.Benefits of living in the country 4.impact on the rural economy
Answer:
1.Why rural settlements have declined
Rural settlements have declined because they offer less economic opportunities. In rural areas, the basic activity is agriculture, which tends to pay less than manufacturing or services, and that, due to mechanization, needs less workers every decade.
2.reasons why city dwellers opt for the country
Sometimes city dwellers opt to move out for the country either because they find employment there, or can work remotely, Living in the country is usually cheaper than living in the city, and can also be more desirable to many people who prefer a quiet enviroment.
3.Benefits of living in the country:
As said above, one benefit is in lifestyle: the country is quiet, calm, and cheap. It has higher quality air, and less polution overall. Many people also find small country communities more socially desirable than the large communities that can be found in cities.
4.impact on the rural economy
City dwellers moving for the country benefits the rural economy. City dwellers bring their incomes, and they support the local community businesses. New comers can also help revitalize areas whose population is dwindling.

Humans and their close relatives (hominins) have been around for roughly 5 million years. What percentage of geologic time is represented by the history of this group?
Answer:
Approximately 0.11% of the geological time.
Explanation:
Evidence from radiometric dating indicates that Earth is about 4.54 billion years old.
If humans and their close relatives (hominins) have been around for roughly 5 million years, the the fraction of this time to the geological time is calculated below
4.54 billion years = 4.54 x 10^9 years
5 million years = 5 x 10^6 years
percentage = [tex]\frac{5*10^{6} }{4.54*10^{9} } *100%[/tex] ≅ 0.11% of the geological time.
