Chemical Erosion is defined as:

• The physical breakdown of rocks without changing their chemical composition.

• The process by which rocks are broken down by chemical reactions.

• The movement of sediment from one place to another.

• The formation of new rocks from existing ones.

Physical erosion is defined as:

• The breakdown of rocks and minerals by chemical reactions.

• The movement of sediment by wind, water, or ice.

• The physical breakdown of rocks and minerals without changing their chemical composition.

• The formation of new minerals from existing rocks.

Tectonic Plates are defined as:

• large slabs of Earth's lithosphere that move over the asthenosphere

• small pieces of rock found in the Earth's crust

• layers of atmosphere surrounding the Earth

• bodies of water on Earth's surface

The definition of Continental Drift is:

• The gradual movement of continents across the earth's surface through geological time.

• The sudden movement of tectonic plates causing earthquakes.

• The process of mountain formation due to tectonic activity.

• The erosion of continental landmasses by wind and water.

Pangea is defined as:

• A supercontinent that existed during the late Paleozoic and early Mesozoic eras

• A type of dinosaur

• A theory about the origin of the universe

• A type of ancient plant

Subduction is defined as:

• The process of one tectonic plate moving under another

• The formation of new oceanic crust

• The movement of tectonic plates away from each other

• The collision of two tectonic plates

The definition of Lithosphere is:

• The rigid outer layer of the Earth, consisting of the crust and upper mantle.

• The liquid layer of the Earth's core.

• The gaseous envelope surrounding the Earth.

• The innermost layer of the Earth.

The asthenosphere is defined as:

• The rigid outer layer of the Earth

• The semi-fluid layer beneath the lithosphere

• The solid inner core of the Earth

• The gaseous outer layer of the Earth
