Earth's Structures

The process by which rocks are broken down chemically or physically is known as:

• Weathering
• Erosion
• Deposition
• Transportation

When wind, water, or ice leave materials in a location, this is known as:

• Weathering
• Erosion
• Deposition
• Transportation

The most important factors in determining the rate of weathering are - 

• carbon dioxide and acid rain
• abrasion and acids from plant roots
• animal actions and oxygen
• rock type and climate

• when the plant moves water from the roots to the leaves

A piece of land surrounded by water.

• Island
• Peninsula
• Gulf

How does a delta form?

• a river slowing down
• it's just a river that empties into an ocean or lake
• the current of the river speeds up at the mouth causing sediment to wash away
• the current of the river slows down causing sediment to deposit
