What is the greenhouse effect?

• The process by which the Earth's surface absorbs longwave radiation from the Sun.

• The process by which the Sun's energy warms up the planet.

• The process by which the Earth's atmosphere absorbs 90% of longwave radiation.

• The process by which greenhouse gases trap heat and make the Earth warmer.

How do human activities impact biodiversity?

• Human activities threaten biodiversity by destroying natural landscapes, polluting the environment, introducing non-native species, and consuming large amounts of resources.

• Human activities have a positive impact on biodiversity by creating new habitats and increasing the number of different species in an area.

• Human activities have no impact on biodiversity as it is solely determined by natural processes.

• Human activities only impact biodiversity in a negative way by reducing the number of different species in an area.

What is one way that matter cycles within an ecosystem?

•  Energy enters an ecosystem when plants carry out photosynthesis.

• Matter is stored as biomass.

• When animals die, decomposers break down their remains and return the matter back to the soil as nutrients to help plants grow.

• Organic molecules can power the life processes of plants through cellular respiration.

What happens to the particles of a substance when it gains energy?

• They slow down and come closer together.

• They move faster and spread apart.

• They vibrate in place.

• They slide past each other.

What is the relationship between thermal energy and a change in state?

• Thermal energy causes particles to move slower and come closer together.

• Thermal energy has no effect on changes in state.

• A substance gains or loses thermal energy to change its form.

• Thermal energy causes particles to vibrate in place.
