Crash Course Kids: Current Events

What is the primary reason for the formation of different atmospheric currents on Earth?

• The rotation of the Earth around the sun

• The movement of the moon around the Earth

• The uneven heating of Earth's surface

• The uniform temperature across the globe

What is the primary cause of sea breezes?

• Uneven heating of land and water

• Moisture from the ocean

• High pressure over the sea

• Tides pulling air towards the shore

What causes the air to rise at the Equator?

• Cooler temperatures

• Higher air pressure

• Direct sunlight heating the area

• Decreased gravitational pull

What would happen if Earth did not have its current tilt and rotation?

• Ocean currents would reverse direction

• Currents would be more intense

• There would be only two large air cells

• Seasons would not change

What phenomenon occurs at the boundaries of different atmospheric cells?

• Formation of mountains

• Development of jet streams

• Reduction in wind speed

• Creation of oceans

How do jet streams typically move?

• In straight lines from east to west

• In wiggly patterns due to pressure systems

• In circular patterns around high-pressure zones

• From the poles directly to the equator

What is the role of ocean currents in Earth's climate?

• They have no significant impact

• They increase the temperature of the poles

• They help regulate global temperatures

• They prevent the movement of air currents

Tags

Why are the poles much colder than the equator?

• They are farther from the sun

• They have higher air pressure

• They receive less direct sunlight

• They are covered in ice

How does the sun influence Earth's currents?

• By moving the Earth closer and farther

• By providing light only

• By heating different parts unevenly

• By changing the Earth's rotation speed

Why are currents important for Earth's habitability?

• They provide energy for plants

• They prevent extreme temperatures

• They transport nutrients globally

• They create landforms like mountains
