Cycles/Spheres

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. It includes processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What role does photosynthesis play in the carbon cycle?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into glucose and oxygen, thus removing carbon from the atmosphere.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What is combustion and how does it affect the carbon cycle?

Back

Combustion is the burning of organic materials, which releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change.

Front

What is the significance of evaporation in the water cycle?

Back

Evaporation is the process by which water changes from liquid to gas, transferring energy from the surface to the atmosphere and playing a crucial role in weather patterns.

Front

How does condensation contribute to the water cycle?

Back

Condensation is the process by which water vapor cools and changes back into liquid, forming clouds and eventually leading to precipitation.

Front

Why do areas around the equator have consistent temperatures?

Back

Areas around the equator receive direct sunlight throughout the year, leading to minimal temperature variation compared to regions further from the equator.

Front

What is thermal energy and how is it stored in oceans?

Back

Thermal energy is the energy that comes from the temperature of matter. Oceans have a high capacity for storing thermal energy due to their large volume and specific heat capacity.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide and methane in the atmosphere.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.
