Factors That Impact The Earth

Which is not an impact to the ecosystem after a drought?

• Water is scarce and causes organisms to find new sources of water elsewhere.

• Floods will wipe out all the vegetation

• Wind erosion will increase

• Herbivores will have to leave and find food elsewhere

Which of these is NOT an impact to the ecosystem after a hurricane?

• Flooding of the ecosystem

• Poor water quality in the area

• Erosion of beaches

• Fires throughout the area

The process that breaks down rocks and other materials on Earth's surface is called

• soil conservation

• erosion

• weathering

• decomposition

The process in which sediment is moved due to agents such as wind or water is

• Erosion

• Deposition

• Weathering

• Precipitation

Look at the photo provided. Ripple marks like you see in this photo are a result of:

• wind deposition

• water erosion

• erosion by waves

In which locations are sand and particles being moved by wind the dominant type of erosion?

• deserts and beaches

• coniferous and deciduous forests

• glaciers and moraines

• mountain peaks

Which of the following agents is the usually responsible for the formation of canyons?

• Gravity

• Wind

• Flowing water

• Rainfall

The use of pesticides and fertilizers must be carefully monitored because of the effect they can have on the environment.

Which of the following is a possible negative effect of the use of these chemicals on the environment?

• Runoff with these chemicals into lakes and streams causes too much algae growth.

• Overusing these chemicals will result in plants not being able to grow.

• These chemicals are expensive to produce.

• Runoff will cause too many plants to grow on the side of the road.
