Unit 3 Study Guide

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass. It occurs when the forces transporting the material lose energy and can no longer carry the load.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind or water flow and then transported and deposited in other locations.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals at the Earth's surface through processes such as temperature changes, water, ice, and biological activity.

Front

What is acid rain?

Back

Acid rain is precipitation that has a lower pH than normal, often caused by pollutants in the atmosphere, which can lead to the deterioration of buildings and natural landscapes.

Front

What is the role of plant roots in weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to split apart, which is a form of mechanical weathering.

Front

What is the difference between erosion and deposition?

Back

Erosion involves the removal and transport of materials, while deposition is the process of laying down or settling those materials in a new location.

Front

What is the impact of strong storms on beaches?

Back

Strong storms can lead to erosion of beaches by removing sand and sediment, which can change the shape and size of the beach over time.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water, acids, or other chemicals, leading to the breakdown of the rock.

Front

What is abrasion?

Back

Abrasion is the process of scraping or wearing away of rocks and surfaces through friction, often caused by wind, water, or ice carrying particles.
