Explanation When the half of the Earth is facing the Sun, it experiences Day , as the Sun's light illuminates that region. The other half of the Earth , facing away from the Sun, experiences Night.

Explanation During Summer in the Northern Hemisphere , the days become longer and the nights become shorter due to the Earth's axis being tilted towards the Sun . This results in more direct sunlight and longer periods of daylight.

Explanation In Winter , days become shorter and nights become longer, due to the Earth's axis being tilted away from the Sun. Resulting in less direct sunlight reaching the Northern Hemisphere .

Explanation The revolution of the Earth around the Sun causes the changing seasons, including Summer and Winter. As the Earth's axis is tilted and different parts of the planet receive varying amounts of sunlight throughout the year.

Explanation The Earth's axis is an imaginary line that runs through the North Pole and the South Pole , around which the Earth rotates. It is an imaginary reference point , not a physical object or shape.

Explanation The Earth completes a day in a Solar day , which is approximately 24 hours. This is the time it takes the Earth to rotate once on its axis, causing day and night to cycle.

Explanation The Earth rotates on its axis , completing one full rotation in 24 hours . This is the equivalent of 1,440 minutes or 86,400 seconds . This rotation is what gives us day and night, as different parts of the planet face towards or away from the Sun.

Explanation The rotation of the Earth on its axis causes day and night. As different parts of the planet face towards or away from the Sun.

Explanation The rotation of the Earth on its axis causes day and night. As different parts of the planet face towards or away from the Sun. Explanation The orbit of the Earth around the Sun is an ellipse , meaning that it is an elongated circle , with the Sun located at one of the two foci (plural of focus) of the ellipse. This means that the distance between the Earth and the Sun varies throughout the year. With the closest point (perihelion) occurring around early January. With the farthest point (aphelion) occurring around early July . Explanation An iron nail/steel rod can be magnetized by passing an electric current around it , a process known as electromagnetic induction. This is the principle behind electromagnets.
