What is thermal energy transfer?

Back

Thermal energy transfer is the process of heat moving from one object to another due to a temperature difference.

Front

How does thermal energy transfer occur between a cold object and a warmer object?

Back

Thermal energy is transferred from the warmer object to the colder object until they reach the same temperature.

Front

What is competition in ecology?

Back

Competition in ecology refers to the struggle between organisms for limited resources such as food, water, and space.

Front

Do only animals compete for resources?

Back

No, both plants and animals compete for resources.

Front

What role does wind play in shaping the earth's surface?

Back

Wind can break rocks, carry them, and deposit them in new locations, contributing to erosion and sediment transport.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals through natural forces such as wind, water, and temperature changes.

Front

How can water temperature affect the weathering of rocks?

Back

Different water temperatures can influence the rate at which rocks weather, with warmer water often increasing the rate of chemical reactions.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increasing light intensity generally increases the rate of photosynthesis, up to a certain point.

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis by collecting data under controlled conditions.
