Weather Things: Seasonal Changes

The video explores how seasonal changes are visible from satellites, highlighting the transition of the Great Lakes and Smokey Mountain National Park through different seasons. It explains the role of sunlight in controlling weather patterns and the formation of sea ice in the Arctic. The concept of the polar vortex is introduced, describing its impact on cold air movement. The video also covers wind patterns and their influence on weather systems, and concludes with an explanation of the seasonal differences between the Northern and Southern Hemispheres due to Earth's tilt.

What natural phenomenon is responsible for the seasonal changes observed in the Great Lakes and Smokey Mountain National Park?

• The Earth's magnetic field

• The gravitational pull of the moon

• The varying amounts of sunlight

• The rotation of the Earth

What is the polar vortex primarily composed of?

• A series of thunderstorms

• A band of powerful winds

• A cluster of low-pressure systems

• A large mass of cold air

How does the polar vortex affect weather in middle latitudes?

• It brings strong winds to the ground

• It causes record heat waves

• It allows Arctic air to move southward

• It stabilizes temperatures

What role do low-level winds play in daily weather changes?

• They create thunderstorms

• They mix the air near the ground

• They form hurricanes

• They stabilize atmospheric pressure

Why are the seasons in the Southern Hemisphere offset by six months compared to the Northern Hemisphere?

• The Earth's orbit is elliptical

• The Southern Hemisphere receives more sunlight

• The tilt of the Earth's axis

• The Southern Hemisphere is closer to the Sun
