Earth Layers and Plate Tectonics

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the tectonic plates are moving towards each other

• the continental crust is melting

• the more dense oceanic crust is subducting

• an ocean ridge is forming

How is the crust DIFFERENT from the other layers of the Earth?

Which of these layers is ALL solid iron and nickle?

• inner core

• outer core

• lithosphere

• mesosphere

We live in an area without many earthquakes because _____

• We live near a major fault line

• We live near the boundary of 2 tectonic plates

• We live near the middle of the North American Plate

• We live near the Pacific Plate

As scientists explore deeper and deeper into Earth's crust, what have they noticed about temperature and pressure?

• both temperature and pressure decrease

• both temperature and pressure increase

• pressure increases while temperature decreases

• temperature increases while pressure decreases

This type of plate boundary is when two plates move apart.

• Convergent

• Transform

• Divergent

• Subductive

How are the crust and the inner core ALIKE?

• • They are both solid.

• • They both have the same temperature.

• • They are both under the same pressure.

• • They are both very close to the center of the Earth.
