Explanation:
If a rock started with 1,000 atoms of a parent but now contains 250 atoms, how many half lives have passed?
a. 0.5 half lives.
b. 1 half life.
c. 2 half lives.
d. 0.25 half lives.
Answer:
Option C. 2 half lives.
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
Half-life is defined as the time taken for the substance to reduce to half its original side. Mathematically, it can be obtained as follow:
N = 1/2ⁿ × N₀
N is the amount remaining.
n is the number of half-lives.
N₀ is the original amount.
Using the above formula, we can obtain the number of half-lives as follow:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
250 = 1/2ⁿ × 1000
Cross multiply
250 × 2ⁿ = 1000
Divide both side by 250
2ⁿ = 1000/250
2ⁿ = 4
Express 4 in index form
2ⁿ = 2²
n = 2
Therefore, it will take two (2) half lives for the amount to get to 250 atoms.

In case the question gets cut off: which world map below shows the locations of major plate boundaries where most earthquakes and volcanoes occur on earth?
Answer: folding, followed by erosion
Explanation:
What are three differences between brittle and plastic strain (may include both characteristics of the strain as well as the conditions and locations where each type of strain occurs), and give an example of the type of structure (deformation feature) associated with each type of strain. Make sure you clearly identify which type of strain is associated with each different trait and feature.
Answer:
elastic deformation: the rock returns to its original shape when the stress is removed.
plastic deformation: the rock does not return to its original shape when the stress is removed.
fracture: the rock breaks.
Explanation:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries.
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.
When forces are parallel but moving in opposite directions, the stress is called shear (figure 2). Shear stress is the most common stress at transform plate boundaries.
Stress In Earth’s Crust
Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.

In case the question gets cut off: which world map below shows the locations of major plate boundaries where most earthquakes and volcanoes occur on earth?
Answer:
The map labeled with 1 shows the major plate boundaries and where most of the earthquakes and volcanoes occur.
Explanation:
The map labeled with number 1 is showing us the plate boundaries. This can easily be confirmed as the lines that are drawn are in the exact same places where the plate boundaries are located. The plate boundaries are the places that are tectonically the most active on Earth, with earhtquakes and volcanoes being a regular occurrence.
Not all plate boundaries though have around the same intensity of earthquakes or number of volcanoes. This is due to the difference in plate boundaries. At the convergent plate boundaries (depending is it between two continental, continental and oceanic, or two oceanic) there can be the formation of volcanoes or mountain ranges, with earthquake activity varying a lot. At transform boundaries, there isn't volcanic activity but there are a lot of earthquakes. At divergent boundaries, earthquakes are rare, but there is intense and constant volcanic activity.
Earth has been cooling since its formation, if this is the case, why is it still hot inside?
A Peridotite xenoliths
B Planetesimals crashing into each other
C Radioactive decay
D Seismic waves
Answer:

g) make two sentences for each of the following using
too and using not... enough
youcan't drinkwine. It's expensive.
This question is incomplete. Here's the complete question.
Make two sentences for each of the following using: (i) too, and (ii) not……. enough.
You can't drink wine every day. It's expensive
Answer:
You can’t drink wine every day. It’s expensive.
Wine is too expensive to drink every day.
Wine is not cheap enough to drink every day.
Explanation:
Not enough and too are used to describe something as inadequate.
If the amount of something is more than what we would like we can use the too + adjective form, which only applies in negative circumstances, such as the wine being too expensive. But we can also use the not + adjective + enough form to talk about something that hasn´t reached the desired level.
HOW DOES ALTITUDE AFFECT YOUR BREATHING?
Answer:
In higher altitudes, the air is usually colder, less dense, and has less oxygen molecules. This means that if you were there, you would need to take more breaths to get the same amount of oxygen as you would at lower altitudes. Higher elevation makes it even harder to breathe.
Explanation:
Hope this info helps!
Explain how plate tectonics and/or process of weathering, erosion, and deposition have shaped peninsula
Answer:
The material moved by erosion is sediment. Deposition occurs when the agents, usually wind or water, of erosion lay down sediment. Deposition changes the shape of the land. Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.

Do you think migration was a voluntary move or involuntary? Why?
Answer:
People who flee persecution and violence in their own country are considered asylum seekers while the people who decide to move to another country in order to seek employment and better life opportunities are considered migrants. Migrants can be legal, moving threw documentation. Migrants are usually people with a strong resources in order to prepare their journey and arrival in the country of the destination. They save money, they gather the information about the trip and the destination and about the potential employment there, like how mast Europians or Asians come to america. They speak to friends and family at the destination who will help them upon arrival. They may speak to travel agents, potential employers at destination or middlemen of different sorts. They may try to learn the language of the destination country. In short, migrants clearly make decisions and take up the actions in order to prepare for their migration. This does not necessarily mean their migration is voluntary. The reasons for leaving their country of origin may have to do with circumstances that are beyond their the control. Migrating is not a decision taken easily, it involves high costs. They may do this to help family
It can be both
People either can be made to move involuntarily, or forced, or are put in situations that encourge relocation, or reluctant, or if they choose to migrate ,or voluntary.
Summer and Winter are reversed in time between the Southern and Northern Hemispheres. (2 points)
True
False
Answer:
True
Explanation:
The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere. This means that in Argentina and Australia, winter begins in June. The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22.

The Earth is heated by light from the Moon.
True
False
Answer:
The moon is not very reflective so the earth only receives a very small amount of "light" reflected that was incident on the moon. Some of this reflected light may be infra-red (heat), but even if it is not some of the visible light reflected will be absorbed by the what it lights up on the earth.
Explanation:
false
What do you know about the rock cycle and the three type of rocks?
Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material
