SEV1 & SEV2 Review

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. They include carbon dioxide, methane, and water vapor.

Front

How do greenhouse gases affect the greenhouse effect?

Back

Greenhouse gases allow sunlight to enter the atmosphere, but they trap heat that is reflected back from the Earth's surface, preventing it from escaping into space.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where all living organisms (biotic factors) and their physical environment (abiotic factors) exist.

Front

What principle explains why a cold drink warms up when left on a table?

Back

The Second Law of Thermodynamics states that heat naturally flows from warmer surroundings to cooler objects.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the variety of species, genetic variation, and ecological communities.

Front

What is the difference between a community and an ecosystem?

Back

A community is made up of different species living together in a specific area, while an ecosystem includes both the community and the abiotic factors that interact with it.

Front

What is the role of carbon dioxide in the greenhouse effect?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the greenhouse effect and helping to maintain Earth's temperature.

Front

What is the First Law of Thermodynamics?

Back

The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of an abiotic factor in an ecosystem?

Back

Examples of abiotic factors include sunlight, temperature, water, and soil.

Front

What is the significance of water vapor as a greenhouse gas?

Back

Water vapor is the most abundant greenhouse gas and plays a crucial role in regulating Earth's temperature by trapping heat.
