Earth's Atmosphere & Weather Review

What is the atmosphere?

• The layer of water that surrounds the planet

• The thin envelope of gasses that surrounds the planet

• The solid crust on which we live

• The collection of all ecosystems on Earth

What are the primary gases that make up the Earth's atmosphere and their percentages?

• 78% Oxygen, 21% Nitrogen, 1% trace gases

• 78% Hydrogen, 21% Oxygen, 1% trace gases

• 78% Nitrogen, 21% Oxygen, 1% trace gases

• 78% Carbon Dioxide, 21% Nitrogen, 1% trace gases

What is air pressure?

• The force of gravity pulling on the atmosphere

• The force exerted by the atmosphere when it is heated

• Each molecule that makes up the atmosphere exerts a small amount of force when it collides with other particles or a surface

How does air density relate to air pressure?

• Air density is not related to air pressure

• Air density decreases as air pressure increases

• Air density decreases at higher altitudes, leading to less pressure

Which temperature of air is less dense and tends to rise?

• Cold air

• Warm air

• Humid air

• Dry air

What is one significant feature of the thermosphere?

• It is the layer where weather occurs

• It protects us from meteoroids

• We find auroras and satellites here

• It is where the ozone layer can be found

What does the absorption of solar energy by the atmosphere help the Earth to do?

• It causes Earth's surface temperatures to become extremely variable

• It leads to the depletion of the ozone layer

• It causes Earth's surface temperatures to remain relatively stable and constant

What is wind?

• The rotation of the Earth on its axis

What is the main difference between sea breezes and land breezes?

• Sea breezes occur at night; land breezes occur during the day

• Sea breezes are caused by the moon; land breezes are caused by the sun

• Sea breezes come from the land; land breezes come from the sea

• Sea breezes occur during the day; land breezes occur at night
