Explanation:
Help! Quicklyyyy! Easy science thing.
Answer:
A year too late..
Explanation:
The picture shows a diagram of Earth's layers.
What is happening at point W?
A. Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.
B. Water in the mantle is being heated by the hot crust, which causes it to sink toward the core where it cools, the convection circuit pulling the tectonic plates.
C. Energy from the Sun heats the crust, which conducts heat into the mantle, causing the magma to warm and sink toward the core, pulling the tectonic plates.
D. Energy from the Sun heats the crust, causing it to shift and pull the tectonic plates, which uses friction to heat the magma in the mantle.
Answer:
It is A. Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.
Why does the Earth spin faster at the equator than the poles?
a
Due to the temperature differences on Earth, the land/sea near the equator goes at a faster rate. The Earth spins faster there only during the summer months.
b
The Earth is much wider at the equator than at the poles. It must cover a larger distance in the same amount of time (24 hours).
c
Due to the tilt of the Earth on its axis, the equator gets more sunlight -- therefore making it spin faster.
Answer:
Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.

I need help with the question in the photo!!
Answer:
a semi-crystalline structure is formed, which holds the water molecules apart, making ice less dense than liquid water, such that it floats. This means that it insulates the water beneath, allowing organisms in the liquid water to survive. Cohesion is the tendency of molecules within a substance to ‘ stick together
explanation:
Is there a relationship between cohesion and volume?
Why do you think the Na+ ion is smaller than a neutral Na atom? Why do you think the Cl - ion is larger than a neutral Cl atom?
Answer:
Na+ ion is smaller than a neutral Na atom in the ion there was one more proton which will attract electron bring it closer to the center making the atomic radius smaller. Therefore making a Na+ ion is smaller than a neutral Na atom Explanation:
yes

The Brahman cattle have good resistance to high temperature, but its meat is poor and tough to eat. The English shorthorn cattle, on the other hand, have good meat, but poor resistance to high temperatures. Farmers formed the Santa Gertrudis cattle by breeding Brahmans with English shorthorns. This new type of cattle has good meat and resistance to high temperatures. Which of the following best describes the process used to produce the Santa Gertrudis cattle?
A.
genetic engineering
B.
inbreeding
C.
natural selection
D.

When an earthquake occurs, two different types of waves are generated. These waves are called P waves and S waves. Examine the diagram, which shows how the waves travel through Earth. Which statement provides the best evidence of Earth’s structure, based on the information in the diagram?
A. The bending of S-waves shows that Earth has both an outer and an inner core.
B. Earthquakes provide no information because they cannot be detected all over Earth.
C. S-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
D. P-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
Answer:
Since S-waves do not travel through liquids, the evidence shows that Earth has an outer core layer made of liquid.

Summarize the Natural Processes of weathering ,erosion, and deposition
Answer:
I won’t do it in paragraph form cuz it will look very choppy but here you go:
Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.
Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.
Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)

the atomic number of an element is the number of ______ plus the number of _____ found in the element's nucleus.
Answer:
protons and electrons
Explanation:
The symbol for an atom can be written to show its mass number at the top, and its atomic number at the bottom. To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.

Elements in the same period are similar in that
same number of valence electrons of same number of energy shells
Answer: I believe this is the answer: The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Good luck on assignment! :)
Answer: The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
