A researcher is analyzing the composition of the soil’s horizons near her house. She gathered a sample of each soil horizon and placed it in a beaker. Unfortunately, she failed to label each beaker and cannot recall which sample contains which soil horizon. A description of the contents of each beaker is presented in the data table below. Based on your knowledge of the soil horizons, how should the researcher label each soil horizon beaker?
Beaker 1 = Bedrock
Beaker 2 = Horizon C (parent material)
Beaker 3 = Horizon B (subsoil)
Beaker 4 = Horizon A (topsoil)
Beaker 1 = Bedrock
Beaker 2 = Horizon B (subsoil)
Beaker 3 = Horizon A (topsoil)
Beaker 4 = Horizon C (parent material)
Beaker 1 = Horizon C (parent material)
Beaker 2 = Horizon B (subsoil)
Beaker 3 = Horizon A (topsoil)
Beaker 4 = Bedrock
Beaker 1 = Bedrock
Beaker 2 = Horizon A (topsoil)
Beaker 3 = Horizon B (subsoil)
Beaker 4 = Horizon C (parent material)

To prevent the loss of nutrients from the soil, farmers use conservation practices to make sure their crops are sustainable. Why should farmers continue using these practices?
Farmers should continue to use these practices in order to conserve the topsoil. The topsoil contains weathered rock which supports plant growth.
Farmers should continue to use these practices in order to conserve the subsoil. The subsoil contains weathered rock which supports plant growth.
Farmers should continue to use these practices in order to conserve the topsoil. The topsoil contains organic matter which supports plant growth.
Farmers should continue to use these practices in order to conserve the subsoil. The subsoil contains organic matter which supports plant growth.

Tommy’s class is investigating soil conservation. He believes that soil is just dirt and has no importance to humans on earth. Tommy’s teacher selects four students to respond to Tommy’s claim. Which statement explains why Tommy’s thoughts are wrong?
Student A says soil is vital for life on earth because it contains small mineral fragments and flowers.
Student B says soil is vital for life on earth because it contains small mineral fragments, organic material, water, and air that can support the growth of vegetation.
Student C says soil is vital for life on earth because it contains small mineral fragments, inorganic material, water, and air that can support the growth of vegetation.
Student D says soil is vital for life on earth because it contains small mineral fragments, inorganic material and flowers.
