JH SCI CHP 5: Lesson 6 Tectonic Plate Movement

As the leading edge of a tectonic plate moves back into the Earth, gravity can assist its movement downward. This is known as what?

• Erosion
• Expansion
• Extrusion
• Slab pull

The process by which heat from the Earth's interior causes magma to rise and sink is known as what?

• Reflection
• Absorption
• Diffusion
• Thermal Convection

What are tectonic plates?

• Small fragments of the Earth's atmosphere that collide with each other
• Giant rocks floating in space
• Layers of the Earth's crust that never move
• Large pieces of the Earth's lithosphere/crust that move and interact with each other

When the mantle pushes the edges of a tectonic plate higher, gravity can pull downward on it, causing the plate to move. This is known as what?

• Volcanic eruption
• Mantle convection
• Plate tectonics
• Ridge push

Breaks in the Earth's crust where plates shift and move are called what?

• fissures
• faults
• crevices
• cracks
