Monsoon Winds and Their Effects

The video explains the southwest monsoon, a key weather phenomenon in India, occurring from June to September. It arrives in two branches: Arabian Sea and Bay of Bengal. The monsoon is driven by temperature differences between land and sea, with land heating faster. This creates a low-pressure area, drawing moist sea air inland, causing rain. The Western Ghats receive heavy rainfall due to this process. The monsoon's strength is linked to temperature differences, with hotter land increasing moisture and rainfall.

Which direction do the southwest monsoon winds originate from?

• Northwest

• Southeast

• Southwest

• Northeast

Which state in India is the first to receive the southwest monsoon rains?

• Tamil Nadu

• Kerala

• Goa

• Maharashtra

What causes different seasons on Earth?

• Earth's rotation speed

• Axial tilt of the Earth

• Distance from the Sun

• Gravitational pull of the Moon

Why does land heat faster than water?

• Land is more reflective

• Water absorbs more solar radiation

• Land is solid and opaque

• Water is denser than land

What is the primary reason for the arrival of the southwest monsoon?

• Ocean currents

• Earth's rotation

• Temperature differences between land and sea

• Wind patterns

What happens to warm air as it rises from the landmass?

• It creates a low-pressure region

• It creates a high-pressure region

• It remains at the same altitude

• It cools and sinks

What is the term for the air flow from sea to land due to pressure differences?

• Land breeze

• Monsoon wind

• Sea breeze

• Trade wind

What geographical feature does the southwest monsoon first encounter on the western coast of India?

• Eastern Ghats

• Himalayas

• Western Ghats

• Vindhya Range

What effect does the Western Ghats have on the monsoon winds?

• They deflect the winds

• They cause the winds to rise and cool, leading to rainfall

• They have no effect

• They cause the winds to speed up

What is directly proportional to the strength of the monsoon wind?

• Wind speed

• Ocean depth

• Humidity levels

• Temperature differences between land and sea
