What is the atmosphere?

• A layer of water surrounding the Earth.

• The solid outer layer of the Earth.

• An envelope of air surrounding the Earth.

• The molten core of the Earth.

How does pressure exerted by a liquid change with depth?

• Pressure decreases with increasing depth.

• Pressure remains constant regardless of depth.

• Pressure increases with increasing depth.

• Pressure is only exerted at the surface.

• Exosphere

• Thermosphere

• Mesosphere

• Troposphere

Why do objects on Earth's surface not collapse under the immense atmospheric pressure?

• Atmospheric pressure only acts downwards.

• The objects are too strong to be affected by pressure.

• Atmospheric pressure is balanced by an equal pressure acting in all directions.

• The Earth's gravity counteracts the atmospheric pressure.
