What is the study of the natural features of the earth and the influence that these features have on people?

Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it.

What are the processes that shape and change our environment?

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth’s surface.

What are the four physical processes?

Physical processes are the natural forces that change Earth’s physical features, including forces that build up and wear down Earth’s surface. You have a thorough understanding of how four physical processes—tectonic movement, volcanic activity, erosion, and glaciation—have shaped Earth’s surface.

What are some examples of physical processes?

Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density. An example of a physical change is the process of tempering steel to form a knife blade.

Which event is an example of chemical weathering?

Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.

What are the similarities and differences between weathering and erosion?

When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.

What are the similarities between erosion and deposition?

Erosion and deposition are similar in that they are both natural processes that involve the action of water, ice and wind.

Which best describes how mechanical and chemical weathering work together?

Chemical weathering is the breakdown of rock by chemical processes. How do mechanical and chemical weathering work together to speed up the weathering process? Mechanical weathering breaks rocks down into smaller pieces. This gives the rock a larger surface area for chemical reactions to take place.

What is the most important mechanical weathering process?

The most important agents of mechanical weathering are: The decrease in pressure that results from removal of overlying rock. Freezing and thawing of water in cracks in the rock. Formation of salt crystals within the rock.

What are the different factors that affect mechanical and chemical weathering?

Factors Affecting Weathering. Weathering rates for both physical and chemical weathering processes depend on particle size, exposure, composition, and climate.
