Science Checkpoint 2 Review- 5th grade TEKS

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is the process of valley formation by moving water?

Back

Valley formation by moving water occurs when rivers or streams carve out valleys over time through erosion.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, primarily through processes of burial and compaction.

Front

What is the role of compaction in fossil fuel formation?

Back

Compaction is the process that compresses organic material under layers of sediment, increasing heat and pressure, which eventually transforms it into fossil fuels.

Front

How do broad, flat leaves help plants in a rainforest?

Back

Broad, flat leaves maximize the surface area for absorbing sunlight, which is essential for photosynthesis in the dense canopy of a rainforest.

Front

What is the relationship between butterflies and flowers?

Back

Butterflies interact with flowers for food, as they feed on nectar, which is crucial for their survival.

Front

What do frogs need for breeding?

Back

Frogs need water for breeding, as they lay their eggs in aquatic environments.

Front

What adaptations do plants in the tundra have?

Back

Plants in the tundra are adapted to cold temperatures and often have features like small leaves, thick stems, and deep roots to survive harsh conditions.

Front

What is the difference between abiotic and biotic factors?

Back

Abiotic factors are non-living components of an ecosystem (like water and temperature), while biotic factors are living components (like plants and animals).

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and minerals into smaller particles through physical, chemical, or biological means.
