Heat transfer by convection is caused by differences in what two things:
Thickness and material
Weight and electricity
Temperature and pressure
Mass and density
Land breezes flow from ____ to ____.
east; west
land; water
clouds; jet
water; land
Sea breezes take place during the day because warmer land temperature results in a warmer air mass above the land compared to the cooler air mass over the surface of water.
true
false
Land breeze and sea breezes are caused by the different temperatures between land and water surfaces.
true
false
When air particles gain energy and rise into the atmosphere, how does this affect the air pressure on the earth's surface?
It causes the air pressure to rise creating high pressure.
It does not affect the air pressure on the earth's surface.
It causes 6th grade students to forget to do their homework.
It causes the air pressure to drop creating low pressure
What causes differences in air pressure?
even heating of the Earth
Even cooling of the earth
uneven heating of the earth
global warming
Which statement correctly defines wind?
The movement of air from areas of low pressure to areas of high pressure
The movement of air to a colder area in the atmosphere.
The movement of air from areas of high pressure to areas of low pressure.
The movement of air pushed around and bouncing off Earth's surface.
Global winds are bands of high pressure and low pressure found at every 30° of latitude. What is the main cause of global winds?
clouds in the atmosphere
conduction in the atmosphere
convection currents in the atmosphere
electricity in the atmosphere
The diagrams show the land, ocean, and heat from the sun interacting during the daytime.
Which diagram correctly shows how air currents are created during daylight hours?
The drawing below shows a sea breeze.
When is this type of wind pattern most likely to occur?
during the night when the surface of the sea cools faster than the land
during the day when the sea is as warm as the land
during the night when the air above land is warmer than the air above the sea
during the day when the land heats faster than the surface of the sea
The following is a process that takes place in the atmosphere.
This process can best be identified as
wind formation
cloud formation
precipitation runoff
static electricity
The arrows in the diagram represent air movement.
This air movement is a result of
particles of pollution entering the air.
the waves pushing against the land.
the sun heating the land and water differently.
water evaporating from plant leaves.
The diagram shows the circular pattern in which warm air and cool air move as the sun warms Earth’s atmosphere.
This pattern of moving air best explains...
how lightening forms.
how radiation works.
how winds form.
how deep ocean currents form.
The image below shows air circulating over a coastal area and nearby ocean.
Which statement is true?
A land breeze forms during the day because the land warms faster than the ocean.
A land breeze flows from the ocean at night because the water cools faster than the land.
A land breeze flows toward the ocean at night because the land and ocean cool at the same time.
A land breeze forms at night because the land cools faster than the ocean.
The drawing below shows a sea breeze.
Which statement about the sea breeze shown is true?
A sea breeze forms during the day because the land warms faster than the ocean.
A sea breeze forms at night because the land cools faster than the ocean.
A sea breeze flows toward the ocean at night because the land and ocean lose heat at the same rate.
A sea breeze flows toward the land during the day because the land and ocean lose heat at the same rate.
Which of these helps to create global wind systems?
Warmer air moves from the poles to the equator.
Colder wind moves from the poles to the equator.
The North Pole receives more solar radiation than the South Pole.
The South Pole receives more solar radiation than the North Pole.
The arrows represent the movement of air above a road on a sunny day.
What is happening at arrow X?
Warm air is rising because warm air is more dense than cooler air.
Cold air is rising because cold air is more dense than warmer air.
Warm air is rising because warm air is less dense than cooler air.
Cold air is rising because cold air is less dense than warmer air.
The diagram shows the patterns of global winds on Earth.
How are northeast trade winds created?
Moist air at 30°N creates large amounts of clouds that block the flow of air from the equator, causing the air to sink and create northeast trade winds.
The Sun’s radiation warms the air at the equator, causing the air to rise, and the rotation of Earth on its axis creates northeast trade winds.
Ships traveling across the ocean between the equator and 30°N change the flow of water, and the wind is cooled by frequent rain to create northeast trade winds.
The oceans at the equator store the Sun’s radiation, generating a flow of cooler winds from the north, creating northeast trade winds.
Study the image of a coastline at night.
What explains why the air is sinking at point Y?
The land is cooler than the water at night, so the air cools, is more dense, and sinks.
The land is warmer than the water at night, so the air warms, is less dense, and sinks.
The land is cooler than the water at night, so the air cools, is less dense, and sinks.
The land is warmer than the water at night, so the air warms, is more dense, and sinks.
Taking into account the average air temperature on Earth, the model shows the expected and actual paths of wind.
What mainly contributes to the direction of wind’s actual path?
revolution of the Moon around Earth
rotation of Earth on its axis
gravitational pull on the gases in the atmosphere by the Sun
number of severe storms in the atmosphere due to Earth’s global temperature

How does water evaporate to begin the water cycle?
Is water more dense than ice?
How does temperature affect global convection currents?
Does air experience a phase change when heated and cooled?
