1. There are three types of tectonic plate boundaries and they includes:
- When two plates slide past each other, they form a <u>transform boundary</u>.
- The <u>divergent boundary</u> occurs when two plates pull away from each other.
- When two plates collide with each other, they formed a <u>convergent boundary</u>.
2. The newest parts of the Earth’s crust is located at mid-ocean ridges.
- The mid-ocean ridge refers to the seafloor mountain system formed by plate tectonics and are the newest parts of the Earth’s crust.
3. Not every earthquake has a foreshock, but every earthquake has aftershock that occur in places far away from the mainshock.

Answer:
C. The greater an element's density, the smaller the amount of it found in the crust
Explanation:
The layering of the Earth happened because of the different densities of the elements from which it was made. The denser elements started to sink deeper, the elements with medium density occupied the central part, and the elements with the smallest density remained at the surface. This resulted in the formation of the three basic layers of the Earth, core, mantle and crust. The core is composed of the densest elements, the mantle of the ones with medium density, and the crust from the ones with smallest density.
Answer:
Explanation:
Angular momentum, L = m v r
areal velocity = 
according to kepler's 2nd law
since, we know that
areal velocity= 
now substituting value of v in areal velocity we get
hence from above equation of rate of change of area swept i.e. areal velocity is proportional to

Explanation:
Answer:
As well as the Earth's position in space, the area of sky we can see at night is determined by our latitude — how far north or south of the equator we are. Places at the same latitude see the same view of the night sky.
