Unit 3 Test Review

Front

What is precipitation?

Back

Precipitation refers to any form of water, liquid or solid, that falls from the atmosphere and reaches the ground, including rain, snow, sleet, and hail.

Front

What is released by the weathering of rocks?

Back

Phosphorus is released by the weathering of rocks.

Front

What is transpiration in plants?

Back

Transpiration is the process by which plants release water vapor from pores (stomata) on their leaves into the atmosphere.

Front

How do animals absorb phosphorus?

Back

Animals absorb phosphorus by consuming plants or other animals that contain phosphorus.

Front

What is percolation?

Back

Percolation is the movement of water through soil and rock layers, allowing it to reach deeper groundwater.

Front

What are the main types of precipitation?

Back

The main types of precipitation include rain, snow, sleet, and hail.

Front

Why is phosphorus important for living organisms?

Back

Phosphorus is essential for the formation of DNA, RNA, and ATP, which are crucial for energy transfer and genetic information.

Front

What role does transpiration play in the water cycle?

Back

Transpiration contributes to the water cycle by returning water vapor to the atmosphere, which can then condense and fall as precipitation.

Front

What factors influence the rate of percolation?

Back

Factors influencing percolation include soil composition, soil structure, moisture content, and the presence of vegetation.

Front

How does weathering contribute to nutrient cycling in ecosystems?

Back

Weathering breaks down rocks, releasing minerals like phosphorus that are essential for plant growth and nutrient cycling.
