Front

What are tectonic plates?

Back

Large pieces of Earth's lithosphere that move and interact with each other, causing geological events like earthquakes and the formation of mountains.

Front

How do mountain ranges form?

Back

Mountain ranges form at the border of two tectonic plates due to their collision or movement.

Front

What is thermal energy?

Back

What are decomposers?

Back

Organisms that break down dead or decaying organisms, returning nutrients to the soil. Examples include earthworms and fungi.

Front

What is a food web?

Back

A food web is a system of interrelated food chains in an ecosystem, showing how energy and nutrients flow between organisms.

Front

What is storm water runoff?

Back

Storm water runoff is water from rain or melting snow that flows over land and can carry pollutants into water bodies.

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally (like solar energy), while non-renewable resources cannot be replaced once used (like fossil fuels).

Front

What is the role of plants in a food web?

Back

Plants are producers that convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is the significance of the Earth's layers?

Back

Earth's layers (crust, mantle, outer core, inner core) have different properties and play a crucial role in geological processes.
