Winter: The Coldest Season Explained

The video tutorial discusses winter, the coldest season, experienced in polar and temperate regions. It explains the origin of the term 'winter' and why only regions above and below the equator experience it. The Earth's tilt causes varying sunlight, leading to seasonal changes. Winter's characteristics include cold temperatures, freezing water bodies, and snow. Meteorological and astronomical patterns define its start. Winter affects animals, prompting migration and hibernation, and inhibits plant growth. Humans face health risks like frostbite and adapt by wearing warm clothing and staying indoors.

What is the primary reason that only regions above and below the equator experience winter?

• The Earth's rotation speed

• The presence of polar ice caps

• The distance from the sun

• The Earth's tilt relative to its orbit

Which of the following is a common method used by countries to define the start of winter?

• Using meteorological patterns

• Based on the average temperature

• By observing animal behavior

• Through public voting

What happens to water bodies when the temperature drops to freezing point during winter?

• They freeze

• They become acidic

• They evaporate

• They expand

How do migratory animals respond to the onset of winter?

• They change their diet

• They grow thicker fur

• They become more active

• They migrate to warmer regions

What is a common health risk for humans during winter?

• Dehydration

• Heatstroke

• Frostbite

• Sunburn
