Soil Erosion01:27

Soil Erosion

Soil ErosionSoil is one of Earth’s most valuable natural resources, but it can be lost through erosion—the process of soil being worn away by wind, water, and human activities like farming, deforestation, and construction. When protective plant cover is removed, the soil becomes more vulnerable to being washed or blown away. Soil erosion reduces the land’s ability to support plant growth, affects water quality, and can even trigger natural disasters like landslides. Learning how and why...
Soil Characteristics01:29

Soil Characteristics

Soil CharacteristicsSoil is an essential part of Earth’s surface that supports plants, animals, and ecosystems. It is made up of minerals, organic matter, water, and air, and its characteristics vary based on climate, rock type, and biological activity. Different soil types affect plant growth, water movement, and human activities like farming and construction. By studying soil characteristics, scientists can better understand ecosystems, manage land use, and support environmental...
The Carbon Cycle01:14

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon Cycle01:26

Carbon Cycle

Carbon CycleThe carbon cycle shows how carbon travels between the air, land, water, and living things. Plants take in carbon dioxide from the air during photosynthesis to make their food. Animals get carbon by eating plants, and they release carbon back into the air through respiration. When plants and animals die, decomposers break them down, returning carbon to the soil and air. Burning fossil fuels also adds carbon to the atmosphere. By studying the carbon cycle, scientists can better...
Soil Horizons and Profiles01:26

Soil Horizons and Profiles

Soil Horizons and ProfilesSoil is made up of different layers, known as soil horizons, which develop over time through weathering, decomposition, and the movement of materials. These layers together form a soil profile, which provides information about soil quality, fertility, and how it supports plant life. Knowledge of soil horizons enables scientists, farmers, and environmental engineers to better protect and manage the land’s valuable soil layers.Science and Engineering Practices (SEP):...
Avoiding Soil Loss01:26

Avoiding Soil Loss

Avoiding Soil LossSoil is essential for plant growth, water filtration, and supporting ecosystems, but it can be lost due to erosion, deforestation, and poor farming practices. When soil is removed faster than it can be replaced, it leads to reduced fertility, increased flooding, and damaged landscapes. Scientists and engineers work to develop solutions to prevent soil loss and maintain healthy land for farming, construction, and natural habitats. Science and Engineering Practices (SEP):...
