What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, which helps to keep the planet warm.

Front

What is Global Warming?

Back

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

Front

What is the role of a generator?

Back

A generator transforms mechanical energy into electrical energy, allowing for the production of electricity from various energy sources.

Front

What is Earth's energy budget?

Back

Earth's energy budget is the balance between the energy Earth receives from the sun and the energy it radiates back into space, which determines the planet's climate.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen, providing energy for the plant.

Front

What is renewable energy?

Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

What is fossil fuel?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, which can be burned for energy, including coal, oil, and natural gas.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates from the Earth's surface, condenses in the atmosphere, and precipitates back to the surface as rain or snow.

Front

What is smog?

Back

Smog is a type of air pollution that is a mixture of smoke and fog, often caused by industrial emissions and vehicle exhaust.

Front

What is ozone depletion?

Back

Ozone depletion refers to the reduction of the ozone layer in the Earth's stratosphere, primarily caused by chemicals like chlorofluorocarbons (CFCs), which can lead to increased UV radiation.
