Tides, Seasons and Eclipses
The moon pulls the tides up to them so that there is high tide. The moon also pulls the earth up to it and the gravitational pull of the earth is larger than the ocean, which means that there is a bit of ocean at the bottom. As long as there are high tides on the top and the bottom of the earth, the two sides will be low tide. The moon is constantly moving around the earth, which means that the high tide and the low tide will be in different places around the earth.
The Earth’s tilt causes seasons. It’s tilt is 23.5 degrees which means that in summer, the sun’s light will be mostly on the southern hemisphere rather than the northern hemisphere. With more light on the southern hemisphere, there will be more daylight hours and warmer weather that means it is summer. As the earth moves around the sun, there will be changes in how much sunlight there is.
A lunar eclipse is one type of eclipse. During the lunar eclipse, the Earth moves between the moon and the sun, which means that the Moon does not get any sunlight. The sun’s light shines onto the earth and creates a shadow on the moon. Lunar eclipses occur at a full moon, which is every 29.5 days.
A solar eclipse is when the Moon is between the Sun and the Earth. The
Sunlight will cast a shadow of the Moon onto the Earth. Solar eclipses happen every new moon which is every 29.5 days.
