Geology and Plate Tectonics Vocabulary

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

Weathering is defined as the process of breaking down rocks, soil, and minerals through natural means. Which of the following best describes this process?

• Erosion

• Weathering

• Sedimentation

• Metamorphism

Chemical Weathering is defined as:

• The breakdown of rocks through physical processes.

• The breakdown of rocks through chemical reactions.

• The movement of rocks and soil by wind and water.

• The formation of rocks from molten magma.
