The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

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

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

A team of geologists wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in Saudi Arabia (1) or in the Arabian Sea (2). Where will the geologists find hard, solid rock?

• Neither under 1 nor 2, because there is sand and gravel under both places.
• Neither under 1 nor 2, because there is water under both places.
• Under both 1 and 2, because Earth's entire outer layer is made of hard, solid rock.
• Only under 1, because Earth's outer layer is made of hard, solid rock under continents but not under the ocean.

Which statement best describes what Earth's outer layer is like underneath the soil and water in the image?

• Underneath both the soil and the ocean, Earth’s outer layer is made of sand and water.

• Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

• Underneath the soil, Earth’s outer layer is made of hard, solid rock. Underneath the ocean, Earth’s outer layer is made of sand.

• Underneath both the soil and the ocean, Earth's outer layer is made of water.

Patterns on this map tell us that...

• volcanic activity and earthquakes can cause damage to buildings and hurt people

• volcanic activity and earthquakes happened in similar areas

• volcanic activity and earthquakes are random

• volcanic activity happened first, then earthquakes, then volcanoes

Wegener’s proposal of a supercontinent was supported by:

• earthquake data
• seafloor magnetism
• rock, fossil, and climate data.
• convection currents in the mantle.
