Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces or sediment.

Front

What is erosion?

Back

Erosion is the movement of sediment from one location to another, often caused by wind, water, or ice.

Front

How do weathering and erosion work together in forming sedimentary rock?

Back

Weathering breaks down rocks into sediment, and erosion transports that sediment to new locations where it can accumulate and form sedimentary rock.

Front

What happens to the weather after a cold front passes?

Back

The weather typically becomes cooler and can be clear.

Front

How long does it take to go from a full moon to a third quarter moon?

Back

It takes about 7 days.

Front

What is a learned behavior in animals?

Back

A learned behavior is an action that an animal acquires through experience or observation, rather than being instinctual.

Front

Which of the following is NOT a learned behavior of birds?

Back

A goose produces eggs with hard shells.

Front

What is the role of sharks in ocean ecosystems?

Back

Sharks are top predators that help maintain the balance of marine ecosystems by controlling the populations of other species.

Front

What happens to the ecosystem if many sharks are removed?

Back

If many sharks are removed, the organisms that they prey on may increase in numbers, potentially disrupting the ecosystem.

Front

What is a cold front?

Back

A cold front is a boundary between a mass of cold air and a mass of warm air, often leading to changes in weather.
