Biogeochemical Cycles Activity

What is Surface Runoff?

Back

Surface runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flows over the earth's surface. It can carry pollutants, including fertilizers, into water bodies.

Front

What is Fertilizer Runoff?

Back

Fertilizer runoff occurs when excess fertilizers applied to crops or lawns wash away into nearby water bodies during rain or irrigation, leading to nutrient pollution.

Front

What is Weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller particles through physical, chemical, or biological means. It is a key part of the rock cycle.

Front

What is Uplift in geology?

Back

Uplift is the geological process where the Earth's crust is raised due to tectonic forces, leading to the formation of mountains and changes in landscape.

Front

What is Nitrification?

Back

Nitrification is the biological process in which ammonia is converted into nitrites and then into nitrates by bacteria in the soil, making nitrogen available to plants.

Front

What is Nitrogen Fixation?

Back

Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) by certain bacteria, making nitrogen accessible to living organisms.

Front

What role do plants play in the biogeochemical cycles?

Back

Plants absorb nutrients and water from the soil, playing a crucial role in the cycling of elements like carbon, nitrogen, and phosphorus through photosynthesis and respiration.

Front

What is the Water Cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, precipitation, and infiltration.

Front

What is the Carbon Cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, crucial for maintaining life on Earth.

Front

What is Erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice, significantly impacting landscapes.
