Weather Things: Causes of Seasons:

The video explores the changes in weather and environment over a year, focusing on the role of seasons. It explains how seasons are defined astronomically rather than meteorologically and discusses the impact of these seasons on weather patterns, particularly in the northern hemisphere. The video highlights summer weather phenomena, including heat waves and tropical storms, and the dangers of extreme heat and humidity. It also addresses urban pollution and the role of ozone in the atmosphere.

What primarily defines the occurrence of seasons on Earth?

• The distance between Earth and the Sun

• The gravitational pull of the Moon

• The tilt of Earth's axis

• The speed of Earth's rotation

Why does the North Pole not get hot despite 24 hours of daylight in summer?

• The sun is too far away

• The sun's angle is less direct

• The North Pole is covered in ice

• The air is too cold

What natural phenomena are more likely to occur near the equator during summer?

• Tornadoes

• Tropical storms and hurricanes

• Blizzards

• Earthquakes

What is a major health risk associated with extreme summer heat?

• Dehydration

• Frostbite

• Heat stroke

• Hypothermia

How does high humidity affect the body's ability to cool down?

• It has no effect

• It increases perspiration

• It speeds up evaporation

• It slows down evaporation

What is the heat index?

• The temperature of the ground

• The temperature felt due to humidity

• The actual air temperature

• The temperature of the ocean

What environmental condition can lead to high levels of ground-level ozone in urban areas?

• Heavy rainfall

• Strong winds

• High pressure and light wind

• Low temperatures
