Earth & Environmental Science

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and ecosystem diversity.

Fossil fuel usage can lead to pollution of natural habitats, which decreases biodiversity and can harm ecosystems.

Runoff is the flow of water, from rain or melting snow, that moves across the ground and can carry pollutants into water bodies.

Infiltration is the process by which water on the ground surface enters the soil, replenishing groundwater supplies.

As warm ocean currents travel north or south from the equator, they typically cool down, become denser, and may sink.

Excessive rain can lead to increased runoff and infiltration, which can cause soil erosion and nutrient loss.

Planting fewer types of crops reduces biodiversity, making crops more vulnerable to pests and diseases.

A major source of air pollution is the large-scale farming of animals, which produces methane and other pollutants.

The greenhouse effect is the warming of Earth’s surface due to the trapping of heat by greenhouse gases in the atmosphere.

Trees help improve air quality, provide oxygen, reduce soil erosion, and support biodiversity by providing habitats.
