The theory of plate tectonics states the following:

• Earth’s asthenosphere is divided into plates, which move.
• Earth’s core is divided into plates, which move.
• Earth’s lithosphere is divided into plates, which move.
• The crust of the earth is molten.

Which of the lettered choices in the soil profile below represents the region with the greatest concentration of organic material?

• A
• B
• C
• D

The water-holding capacity of a soil is LEAST likely to be affected by the addition of which of the following?

• manure
• humus
• clay
• sand

Overgrazing of grasslands can lead to reduced range quality.  Two of the major effects of overgrazing are

• erosion and desertification
• eutrophication and increased methane production
• higher fire potential and increased productivity
• soil compaction and subsidence

Which of the following methods of agricultural irrigation results in the loss of the least amount of water by evaporation?

• Flood irrigation
• Gravity-flow irrigation
• Conventional center-pivot irrigation
• Drip irrigation

This rock cooled on the outside of a volcano and contained air bubbles when it was forming. What type of rock is this?

This rock was formed by lots of fossils that settled on top of each other over time. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

After lots of time, pressure, and heat, you get this kind of rock. What type of rock is this?
