Weathering & Erosion

When does erosion occur?

• Erosion occurs when broken rocks and sediments are picked up and moved to another place by water only.

• Erosion occurs when broken rocks and sediments are picked up and moved to another place by ice, water or wind.

• Erosion occurs when dirt is picked up and moved to another place by ice, water or wind.

• Erosion occurs when ice is picked up and moved to another place by water or wind.

What is weathering?

• The process where ice is worn away or broken down into smaller pieces by wind, water or plants.

• The process where rocks are worn away or broken down into smaller pieces by just wind.

• The process where rocks are built into larger pieces by water and dirt.

• The process where rocks are worn away or broken down into smaller pieces by wind, water or plants.

What are two ways wind can cause erosion?

• Wind causes erosion by blowing water from one place to another.

• Wind causes erosion by picking up and carrying loose particles and dust away.

• Wind causes erosion by keeping particles and dust in one place.

• When flying particles, caused by wind, crash into the land and break off more particles.

What is water erosion?

• Water erosion is when water stays in one place forming a lake.

• Water erosion is when water moves soil and other natural materials from one spot to another.

• Water erosion is when water moves all living things from one spot to another.

• Water erosion is when water creates a natural habitat for amphibious animals.

What is geosphere?

• The solid center of the earth. The hottest part of the earth.

• The liquid part of the earth consisting of water in, on, and around the planet Earth.

• The solid part of the atmosphere.

• The solid part of the earth consisting of the crust and the outer mantle.

What is mechanical weathering?

• Mechanical weathering is the process of creating big rocks that form mountains.

• Mechanical weathering is the process of sand turning into rocks.

• Mechanical weathering is the process of breaking big rocks into little ones.

• Mechanical weathering is the process of cold water forming icebergs.

What is abrasion?

• Abrasion is the mechanical scraping of rock surface by friction between rocks or moving particles during their transport by wind, glacier, waves, gravity, running water or erosion.

• Abrasion is the formation of rocks by particles and other natural materials fusing together during their transport by wind, glacier, waves, gravity, running water or erosion.

What is chemical weathering?

• Chemical weathering is the process by which rocks are broken down by chemical reactions.

• Chemical weathering is the process by which rocks are fused together by chemical reactions.

• Chemical weathering is the process by which rocks are formed by chemical reactions.

• Chemical weathering is the process by which rocks are broken down by wind.

What two ways can temperature impact weathering?

• How fast weathering happens.

• What type of plants are grown in a particular area.

• What type of weathering occurs.

• How much water is in an area.
