Understanding Wind Patterns and Effects

The video explains wind currents, which are caused by air moving from high to low pressure areas. Uneven heating between the equator and poles creates pressure differences, leading to wind circulation. Earth's rotation deflects winds, affecting their direction in different hemispheres. Additionally, land and sea breezes result from temperature differences between land and water, influencing local weather patterns.

What is the primary cause of wind currents?

• Uneven heating of the Earth's surface

• Movement of air from high to low pressure

• Movement of air from low to high pressure

• Rotation of the Earth

What causes the differences in air pressure between the equator and the poles?

• Differences in air temperature

• Differences in humidity

• Differences in altitude

• Differences in wind speed

How does the Earth's rotation affect wind direction?

• It causes winds to travel in a straight path

• It causes winds to deflect to the right in the southern hemisphere

• It causes winds to deflect to the right in the northern hemisphere

• It has no effect on wind direction

In which hemisphere are winds deflected to the left?

• Both Hemispheres

• Southern Hemisphere

• Neither Hemisphere

• Northern Hemisphere

What happens to the air above the land near the equator during the day?

• It is warmed by conduction and rises

• It remains at a constant temperature

• It sinks towards the Earth's surface

• It cools down rapidly

What is the result of the warm air rising above the land near the equator?

• A high pressure area is created

• A low pressure area is created

• A decrease in wind speed

• No change in pressure

What initiates the flow of cool sea breezes towards the land?

• The rising of warm air over the sea

• The sinking of cold air over the land

• The rising of warm air over the land

• The sinking of cold air over the sea

What do the winds from the sea carry with them?

• Cold air

• Heat

• Moisture

• Dust

What is the effect of sea breezes carrying moisture?

• They cause drought

• They decrease humidity

• They bring rain

• They increase temperature

Which factor does NOT contribute to the formation of wind currents?

• Movement of air from high to low pressure

• Constant temperature across the globe

• Uneven heating of the Earth's surface

• Earth's rotation
