11.22 301 ONLY Soil Formation and Characteristics in Different Biomes

This assignment will help you understand the components and formation of soil in various biomes. You will analyze your lab experiment on soil columns and explore how different environmental factors influence soil characteristics.

This section explores the abiotic and biotic components of soil, as well as the process of soil formation. Use the provided diagram to assist in answering the questions.

Identify one abiotic component of soil.

Identify one biotic component of soil.

Describe one biotic and abiotic process that create soil.

In this section, you will analyze the scientific aspects of your lab experiment on soil layers in different biomes.

Identify the scientific question for your soil column lab experiment.

What is the independent variable (IV) in your experiment?

What is the dependent variable (DV) in your experiment?

This section requires you to explain the differences in soil formation and characteristics between grassland and rainforest biomes.

DESCRIBE the differences and similarities between the soil layers in a grassland and rainforest biomes, and how the soil layers that are formed differently, focusing on climate and vegetation.

EXPLAIN why grassland soils are high in nutrients while rainforest soils are low, and why rainforests have higher infiltration rates.

EXPLAIN how climate change may affect the formation of soils in either the grassland or rainforest biome.
