A)
It occurs on June 21.
B)
The Sun is at aphelion.
C)
The South Pole experiences 24 hours of darkness.
D)
The North Pole experiences 24 hours of darkness.

Correct Answer :   The North Pole experiences 24 hours of darkness.

On December 21, the earth is in an equivalent position on the opposite points in its orbit, So the South pole is tipped towards the sun and North pole away from it resulting in 24 hours of darkness at the North pole, as the sun is overhead on the Tropic of Capricorn. This phenomenon is winter solstice; while on June 21, North pole is tipped towards the Sun but the South pole is tipped away from the sun resulting in 24 hours of darkness on the South Pole, as the sun is overhead on the Tropic of Cancer.This phenomenon is summer solstice; while Aphelion is the position of the earth in its orbit when it is at its distant point from the sun.

As water is cooled from 4 deg C to 0 deg C, its density
A)
remains same
B)
zero
C)
decreases
D)
increases

Correct Answer :   decreases

When water is cooled from 4°C to 0°C, its density decreases.
 
When water cools from 4°C to 0°C, ice crystals begin to form because the water is approaching its freezing point. When water freezes, the water molecules form a lattice that increases the volume. As a result, the density decreases. This is why ice will float on top of water; ice has a lower density than the water.
