Earth Science Fall Final Question Pool

Front

What is a dike in geology?

Back

A dike is an intrusive geological feature that forms when magma is injected into fractures that cut across rock layers.

Front

What is frost wedging?

Back

Frost wedging is a weathering process that involves the repeated freezing and thawing of water, causing rocks to break apart.

Front

Which field of study is NOT part of Earth science?

Back

Astrology is NOT one of the main areas of Earth science; the main areas include geology, oceanography, and meteorology.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process where physical forces break rock into smaller pieces without changing its chemical composition.

Front

What does cleavage mean in mineralogy?

Back

Cleavage refers to the tendency of a mineral to break along flat or even surfaces.

Front

What is the main focus of geology?

Back

Geology is the study of the Earth's solid materials, including rocks, minerals, and the processes that shape the Earth.

Front

Define oceanography.

Back

Oceanography is the study of the ocean, including its ecosystems, currents, and the geology of the ocean floor.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is exfoliation in geology?

Back

Exfoliation is a weathering process where layers of rock peel away due to temperature changes and pressure release.

Front

What is the difference between chemical and mechanical weathering?

Back

Chemical weathering involves changes in the chemical composition of rocks, while mechanical weathering involves physical breakdown without chemical change.
