Human Impacts Test Review

Front

What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which heat from the sun is trapped by carbon dioxide and other gases in the Earth's atmosphere, leading to an increase in temperature.

Front

What causes eutrophication?

Back

Eutrophication is primarily caused by the use of fertilizers, which run off into water bodies, leading to excessive growth of algae and depletion of oxygen.

Front

What is Climate Change?

Back

Climate Change refers to long-term changes in all of Earth's weather conditions, including temperature, precipitation, and wind patterns.

Front

What is Point Source Pollution?

Back

Point Source Pollution is pollution that comes from a specific site or cause, such as a factory or sewage treatment plant.

Front

What is a positive human activity for ecosystems?

Back

Planting trees is a positive human activity that can enhance ecosystems by providing habitat, improving air quality, and preventing soil erosion.

Front

What is Global Warming?

Back

Global Warming is the long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels.

Front

What is Nonpoint Source Pollution?

Back

Nonpoint Source Pollution is pollution that does not come from a single, identifiable source, often resulting from runoff from agricultural fields or urban areas.

Front

How do fertilizers impact water bodies?

Back

Fertilizers can lead to nutrient pollution in water bodies, causing algal blooms that deplete oxygen and harm aquatic life.

Front

What is the role of carbon dioxide in the atmosphere?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the Greenhouse Effect and influencing global temperatures.

Front

What are the effects of deforestation?

Back

Deforestation can lead to loss of biodiversity, disruption of water cycles, and increased carbon dioxide levels in the atmosphere.
