Which layer of the atmosphere is the hottest?

• exosphere

• mesosphere

• thermosphere

• stratosphere

The more particles/molecules in a definite volume of air, the

• less mass it has

• greater the air pressure

• lower the pressure

• less dense the air

As you rise upwards in the atmosphere, air pressure

• increases.

• decreases.

• doesn't change.

The atmosphere is

• The layer in which weather occurs.

• The layer that contains the ozone layer.

• The layer of water in the oceans.

• The layers of gases that surrounds Earth.

The two most abundant gases in the atmosphere are

• Carbon Dioxide and Oxygen

• Carbon Dioxide and Nitrogen

• Nitrogen and Oxygen

• Nitrogen and Hydrogen

When climbing a high mountain, you get out of breath because

• The percentage of oxygen in the air increases.

• The air is more dense.

• There is less oxygen in each cubic meter of air.

• Air pressure is greater.

The layers of the atmosphere are classified according to changes in

• altitude.

• density.

• pressure.

• temperature

The layer of our atmosphere in which weather occurs is the

• Troposphere (layer 1)

• Stratosphere (layer 2)

• Mesosphere (layer 3)

• Thermosphere (layer 4)

This is the layer of the Atmosphere where you can also find the Ozone Layer.

• Thermosphere

• Stratosphere

• Troposphere
