• Deposition

• Plate tectonics

• Weathering

Which of the following is a subsurface event that takes place during the rock cycle?

• Melting

• Erosion

• Weathering

• Cementing

Which of the following types of rocks are likely to disintegrate by weathering and erosion?

• Metamorphic rocks only

• Neither igneous rocks nor metamorphic rocks

• Igneous rocks only

• Both igneous rocks and metamorphic rocks

Which of the following types of rocks are likely to be formed due to heat and pressure?

• Sedimentary rock only

• Both sedimentary rock and metamorphic rock

• Metamorphic rock only

• Neither sedimentary rock nor metamorphic rock

Which of the following characteristics of Earth's crust is likely to contribute to geological events?

• Can be broken into many plates

• Has uniform thickness throughout

• Is composed of a single layer that surrounds Earth

• Sits on top of the solid rock of the lower mantle

Which feature of the layers of Earth contributes to the various geological events?

• The lower mantle being made of solid rock

• The lower mantle being relatively hotter

• The crust being of same thickness all over

• The crust being made of a single layer all over

Which of the following is likely to contribute to geological events that take place on Earth?

• Crust undergoing convective currents

• Crust being a single layer that surrounds Earth

• Crust sitting on top of molten rock of the mantle

• Crust being of uniform thickness throughout

Which process transfers heat from inside Earth to its surface?

• Convection currents in crust

• Pulling away of tectonic plates

• Convection currents in mantle

• Drawing in of tectonic plates

What happens during heat transfer within Earth?

• Warmer, more dense material sinks

• Cooler, more dense material rises

• Cooler, less dense material sinks

• Warmer, less dense material rises

What happens when heat from inside Earth is transferred to its surface?

• More dense material is pushed to the crust

• Warmer material is pushed to the crust

• Warmer material is pushed to the outer core

• Less dense material is pushed to the outer core
