Energy on Earth

Front

What is convection in the atmosphere?

Back

Convection is the process by which heat is transferred through the movement of fluids (liquids and gases). In the atmosphere, it powers the circulation of air, leading to weather patterns.

Front

How is energy transferred on Earth?

Back

Energy is continuously transferred by transforming among various forms, such as from solar energy to thermal energy.

Front

What happens when Earth's surface is heated unequally?

Back

Unequal heating of Earth's surface causes atmospheric and oceanic motion, leading to wind and ocean currents.

Front

What is a secondary source of energy?

Back

A secondary source of energy is energy that is derived from primary sources. For example, electricity is a secondary source that can be generated from solar, wind, or fossil fuels.

Front

What role does Earth's hot interior play in the energy budget?

Back

Earth's hot interior is a source of energy, contributing to geothermal energy and influencing geological processes.

Front

Define energy transformation.

Back

Energy transformation is the process of changing energy from one form to another, such as converting kinetic energy to potential energy.

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 in the atmosphere.

Front

What is solar energy?

Back

Solar energy is the energy received from the sun, which can be harnessed for various uses, including heating and electricity generation.

Front

Explain the concept of thermal energy.

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the movement of air, which can be converted into electricity using wind turbines.
