Front

What is the El Nino-Southern Oscillation?

Back

A climate pattern characterized by sea surface temperature changes greater than 0.5°C for more than 5 months across the central tropical Pacific Ocean.

Front

What two factors allow Earth to experience four distinct seasons?

Back

Tilt of axis and rotation around the sun.

Front

What is the correct sequence of layers of the Earth's atmosphere from the surface to space?

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere.

Front

What is the order of convection cells starting from the equator?

Back

Hadley, Ferrell, Polar.

Front

How does the Coriolis Effect influence water movement in the Northern Hemisphere?

Back

Water moves in a clockwise direction.

Front

Define the term 'Coriolis Effect'.

Back

The apparent deflection of moving objects (like air and water) due to the rotation of the Earth.

Front

What is the significance of the tilt of the Earth's axis?

Back

It causes seasonal variations in climate and daylight.

Front

What are Hadley cells?

Back

Convection cells that circulate between the equator and 30 degrees latitude, responsible for tropical climates.

Front

What is the role of the stratosphere?

Back

It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

Explain the concept of thermal stratification in water bodies.

Back

The layering of water in lakes and oceans due to temperature differences, affecting aquatic life.
