A_32: Earth Science Final Exam Review

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What geologic feature is commonly found at a divergent boundary between oceanic crust?

Back

Mid-Ocean Ridge.

Front

What geologic feature is commonly found at a divergent boundary between continental crust?

Back

Rift Valley.

Front

What does the ozone layer protect life on Earth from?

Back

Ultraviolet Rays.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical composition of rocks, often through reactions with water, acids, or gases.

Front

How does physical weathering differ from chemical weathering?

Back

Physical weathering does not change the chemical composition of rocks, while chemical weathering does.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, characterized by steep walls and a central block.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where new oceanic crust is created.

Front

What are ultraviolet rays?

Back

Ultraviolet rays are a type of electromagnetic radiation that can cause skin damage and are blocked by the ozone layer.
