N2

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

Pesticide

Corn is a crop that grows best in soil that drains well. Which of the following soils is best suited to grow corn?

Sandy loam because it has large amounts of sand and less than 20% clay.

The diagram below is an illustration of global atmospheric circulation. Which of the following is the source of energy driving the circulation pattern labeled C in the diagram?

Solar radiation

This layer of Earth's atmosphere contains the ozone layer that absorbs the sun's ultraviolet rays.

Stratosphere

The graph below shows the altitude and temperature for different layers of Earth's atmosphere. Based on the diagram, which of the following identifies a characteristic of the atmosphere between the stratopause and the tropopause?

The ozone layer is in the stratosphere.

Which of the following best explains why the lower portion of the troposphere is warmer than the upper portion?

The surface of Earth absorbs sunlight, heating the lower portion of the troposphere more than the upper part.

Which of the following agricultural practices would most likely lead to improved water quality in nearby streams and rivers?

Using crop rotation in fields

Most of the Earth's deserts are at approximately 30° latitude, north and south, because these latitudes are characterized by

descending dry air currents
