The largest cell in the tricellular model, found from 0 to 30 degrees latitude

• Farrell Cell

• Polar Cell

• Hadley Cell

• Thermohaline circulation

What causes air to be pulled down towards Earth's surface?

• Magnetism

• Gravity

• Atmospheric composition

• Barometric pressure

Which layer of the atmosphere contains the ozone layer?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What impact does global air circulation have on weather?

• It has no significant impact on weather.

• It only affects temperature, not precipitation.

• It distributes heat and creates areas of high and low pressure.

• It causes the Earth to tilt on its axis.

Hot dry air sinks about 30 degrees North and South of the equator. This causes what type of biome to from?

• tropical rainforests

• temperature forests

• deserts

• tundra

Which layer of Earth's atmosphere is closest to the surface?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What is the primary driver of the Hadley Cell circulation?

• Earth's rotation

• Solar heating at the equator

• Ocean currents

• Magnetic fields

Which gas is most abundant in Earth's atmosphere?

• Oxygen

• Carbon Dioxide
