Use the information and images to answer the following question. Students in Earth science class were presented with pictures that show how a land formation was created where a river enters an ocean. Which is the BEST explanation to describe what is forming and why is it developing at this site?

• This model shows a delta formed because of the erosion of sediments where the river flows into the ocean.

• This model shows a delta formed because of the deposition of sediments where the river flows into the ocean.

• This model shows the sea level is slowly falling because the precipitation is less than the rate of evaporation.

• This model shows the sea level is slowly rising because the precipitation is greater than the rate of evaporation.

To prevent the loss of nutrients from the soil, farmers use conservation practices to make sure their crops are sustainable. Why should farmers use soil conservation practices?

• To conserve the topsoil, which contains weathered rocks, will not allow the plants to grow.

• To conserve the topsoil, which contains humus, will not allow the plants to grow.

• To conserve the topsoil, which contains weathered rocks, will allow the plants to grow.

• To conserve the topsoil, which contains humus, will allow the plants to grow.

Use the information and table to answer the following question. A researcher is analyzing the composition of the soil’s horizons near her house. The researcher gathered a sample of each soil horizon and placed it in a beaker. A description of the contents of each beaker is presented in the data table. How should the researcher label each soil horizon beaker?

• A. Beaker 1 = Horizon B (subsoil) Beaker 2 = Horizon C (parent material) Beaker 3 = Bedrock Beaker 4 = Horizon A (topsoil)

• B. Beaker 1 = Horizon A (topsoil) Beaker 2 = Horizon B (subsoil) Beaker 3 = Bedrock Beaker 4 = Horizon C (parent material)

• C. Beaker 1 = Horizon C (parent material) Beaker 2 = Horizon B (subsoil) Beaker 3 = Horizon A (topsoil) Beaker 4 = Bedrock

• D. Beaker 1 = Bedrock Beaker 2 = Horizon B (subsoil) Beaker 3 = Horizon A (topsoil) Beaker 4 = Horizon C (parent material)
