Study Guide for Unit 4 Test (2/9!)

Put the layers of the atmosphere in order from the innermost to outermost.

• Troposphere, Mesosphere, Stratosphere, Thermosphere

• Troposphere, Stratosphere, Thermosphere, Mesosphere

• Troposphere, Stratosphere, Mesosphere, Thermosphere

• Thermosphere, Stratosphere, Mesosphere, Thermosphere

What is an example of radiation?

• The sun warming the Earth

• The water boiling in a pot

• Touching a hot stove

• Air coming through an air vent

Atmospheric pressure is the weight of a column of air above a unit area. A higher atmospheric pressure means that there are more air molecules packed into a certain space. Atmospheric pressure changes as the altitude above Earth changes.

Based on data in the graph, which statement describes the air molecules in the upper atmospheric layers?

• There are more air molecules in the upper layers

• There are fewer air molecules in the upper layers

• There are larger air molecules in the upper layers

• There are no molecules in the upper layers

The graph shows how temperature changes with increasing altitude through Earth's atmospheric layers.

Which statement correctly describes some of the data in the graph?

• As altitude increases, temperature decreases in the stratosphere and mesosphere.

• As altitude increases, temperature increases in the stratosphere and decreases in the mesosphere.

• As altitude increases, temperature increases in the stratosphere and in the mesosphere

• As altitude increases, temperature decreases in both the thermosphere and the stratosphere

Which two layers of the atmosphere are characterized by decreasing temperatures with increasing altitude?

• Mesosphere, Thermosphere

• Thermosphere, Stratosphere

• Stratosphere, troposphere

• Troposphere, mesosphere

Gas in Earth's atmosphere that absorbs most of the damaging high-energy UV radiation from the Sun is known as

• Stratosphere

• Ozone

• Air Pressure

• Climate

The primary source of energy that drives convection within the atmosphere and oceans is

• The Earth's magnetic fields

• The ocean

• The thermal energy from the sun

• The moon

What is an example of convection?

• Cold air coming through an air vent

• A handle on a hot pan

• The sun warming the Earth with it's rays

• Feeling the heat from the sun when sitting near a window

What is the most likely reason why sand at the beach heats up faster than the ocean water?

• Sand radiates heat faster than water

• Sand reflects heat fast than water

• Sand absorbs heat faster than water

• Water reflects the heat faster than sand

Which of the following is correct when convection occurs in the atmosphere?

• Warm air sinks and cold air rises

• Cold air rises and warm air sinks

• Warm air rises and cold air sinks

• Cold air and warm air mix together and sink
