As altitude increases, what happens to the pressure of the air?
The air pressure increases.
The air pressure decreases.
The air pressure stays the same.
The air pressure increases at first, and then it decreases.
The gases that make up Earth’s atmosphere are commonly referred to as air. Approximately what percentage of air is made up of gases other than nitrogen and oxygen?
1%
11%
21%
99%
Look at the following image of a greenhouse. A greenhouse is a building where plants are cultivated. Because a greenhouse traps some of the incoming solar radiation, the air inside is generally warmer than the air outside.
argon
carbon dioxide
nitrogen
oxygen
The following diagram shows the layers of the atmosphere. In which layer does weather happen?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Earth’s atmosphere traps energy from the sun. Which is a direct result of the trapping of energy by Earth’s atmosphere?
Earth has gravity.
Earth has weather.
Earth has moderate temperatures.
Earth’s atmosphere has four layers.
The net flow of energy into and out of the Earth system is the referred to as Earth’s energy budget. Which of the following is the main source of the energy in the Earth system?
explosive volcanic eruptions
kinetic energy from global winds
convection currents in the mantle
electromagnetic radiation from the sun
The picture below shows all three methods of energy transfer. Which of these correctly identifies the three methods of energy transfer?
1: convection 2: radiation 3: conduction
1: radiation 2: conduction 3: convection
1: conduction 2: convection 3: radiation
1: radiation 2: convection 3: conduction
Which of these is not a way in which energy is transferred to Earth from the sun?
conduction
infrared radiation
visible light
x-rays
Which of the following is most responsible for the moving bands of air around Earth that are shown in the picture above?
conduction
convection
Coriolis effect
greenhouse effect
As water is heated by the sun, it becomes less dense and rises. What causes the decrease in the density of warming water?
The water particles move faster, causing the water to expand.
The water particles move slower, causing the water to expand.
The water particles move faster, causing the water to contract.
The water particles move slower, causing the water to contract.
Throughout the day, Matthew and Mei measure the temperature of lake water as it is warmed by the sun. The following table shows their data at four different times. At what time was the thermal energy of the lake water the greatest?
9 a.m.
11 a.m.
3 p.m.
5 p.m.
Which of the following best explains the curvature of the arrows for the westerlies and the trade winds?
The ocean currents create winds flowing in a similar direction to the current.
The Coriolis effect causes the winds to curve that way because the Earth rotates from left to right.
The Coriolis effect causes the winds to curve that way because the Earth rotates from right to left.
The sun is shining and warming the air from the right side of this diagram.
Which of the following describes the general pattern of winds near the equator?
Winds are generally weak because the equator is a region where low and high air pressure atmospheric bands come together.
Winds are generally strong because the equator is a region where low and high air pressure atmospheric bands come together.
Winds are generally strong because the equator is a region of mostly high air pressure.
Winds are generally weak because the equator is a region of mostly low air pressure.
The air above Earth’s surface is at different temperatures. What is responsible for this difference in temperature?
the sun
the moon
landforms
Earth's rotation
Rock and water absorb and release heat differently, causing localized air pressure differences. One result of these differences is land breezes. Which statement is true of land breezes?
They originate in the day and blow toward the land.
They originate in the day and blow toward the water.
They originate in the evening and blow toward the land.
They originate in the evening and blow toward the water.
Winds are named based on different factors. How are winds usually named?
Winds are usually named based on their altitude.
Winds are usually named based on their strength.
Winds are usually named based on the direction in which they are blowing.
Winds are usually named based on the direction from which they are blowing.
The wind in a certain area is blowing from east to west. Which of the following conclusions is most justified by this fact?
The west is experiencing lower air pressure than the east.
The west is experiencing higher air pressure than the east.
The west is experiencing lower air temperature than the east.
The west is experiencing higher air temperature than the east.
The names and molecular structures of four components of the atmosphere are shown in the following figures. Each constitutes a different percentage of Earth’s atmosphere. Which of the four can trap the greatest amount of heat?
At different places on Earth, depending on elevation, air pressure varies. Which of the following reflects air pressure at any point on Earth?
the weight of the atmosphere
carbon dioxide levels in the air
moisture (water vapor) in the air
the strength of Earth’s magnetic field
In which substance will convection happen most efficiently?
a rock
a pool of water
air
