Explanation

• Permanent magnets are materials that retain their magnetism for a long time.
• They are typically difficult to magnetize, but once magnetized, they retain their magnetic properties.

Explanation

• Jupiter takes approximately 4332.62 Earth days to complete one revolution around the Sun.
• Which is the longest revolution period of all the planets in our solar system.

Explanation

• The Earth takes approximately 23 hours, 56 minutes, and 4 seconds to complete one rotation on its axis, which is called a sidereal day.
• This is the time it takes for the Earth to rotate once relative to the fixed stars.
• The extra 4 minutes is due to the Earth's slightly ellipsoidal shape and the effects of the Moon's gravitational pull.

Explanation

The sun rises in the East and sets in the West.

which means that the Earth is rotating from West to East. 

Earth revolves in orbit around the Sun in 365 days, 6 hours, 9 minutes.

with reference to the stars, at a speed ranging from 29.29 to 30.29 km/s.

The 6 hours, 9 minutes add up to about an extra day every fourth year,

which is designated a leap year, with the extra day added as February 29th.

Explanation

• The Earth rotates constantly from West to East.
• Which is why the Sun appears to rise in the East and set in the West.
• This rotation is also the reason why we experience day and night in a 24-hour cycle.

Explanation

When the half of the Earth is facing away from the Sun, it experiences Night, as it is not receiving direct sunlight.

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.
