Daily Reflection Prompt: What causes the different seasons of the year?

The study of the moon, stars and other objects is called….. Astronomy

Why is there night and day? Earth is rotating around the axis It takes 24 hours for the Earth to rotate around its axis

How many days does it take for the earth to rotate around the sun How many days does it take for the earth to rotate around the sun ? (Don’t forget about leap year) 365 ¼ days That is why we add an extra day to Feb every four years.

Why is it warmer at the equator? Because it gets direct sun light

Why is it hotter in the summer and colder in the winter Earth is NOT closer to the sun in the summer When Northern Hemisphere is having summer, Earth is at its greatest distance from the sun. It’s because of the tilt in the earth’s axis

Reasons for the seasons If it is summer time in the Northern Hemisphere is it Summer time in the Southern Hemisphere?

The longest and shortest days of the year are known as S_______ olstice In the Northern Hemisphere The shortest day of the year is December 21 The longest day of the year is June 21

In the Northern Hemisphere During two days of the year, the length of nighttime and daytime are about the same. It is called the Eq_______ uinox In the Northern Hemisphere Vernal Equinox (Spring Equinox) occurs on March 21 Autumnal Equinox occurs on September 23

Myth or Fact: Is it easier to make an egg stand during an Equinox? It is no easier or harder to stand an egg during an Equinox.

How many mile is the diameter of the Earth? About 8000 miles

How many earths can fit inside the sun? The Sun’s diameter is about 870,000 miles The sun’s diameter is more than 100 larger. In fact, the Sun is so big that if it were hollow, you could fit over one million Earth's inside of it

If you were traveling to the sun at 100 miles per hour, how long will it take to get there? 92 million miles away If there was a highway to the sun and you were traveling 100 miles per hour it will take 105 year to reach it. It takes light 8 minutes to travel from the sun to the Earth
