Science why do we have seasons

When the earth is tilted away from the sun we have day. What season is it in the Southern Hemisphere when it is fall in the Northern Hemisphere? Why does the area around the equator stay the same temperature all year?

The equator rotates slower than the poles. The equator remains the same distance from the sun. The equator always receives direct sunlight. The equator has 18 hour days. One rotation of Earth is equal to. What would seasons be like if Earth's axis were straight up and down? Seasons would be the same. Seasons would be more extreme. There would be no seasons.

Where on Earth can you experience entire days of darkness? The Tropic of Capricorn. Young animals become bigger and stronger. Animals have to seek out the food sources that have been ready to spoil over winter. In the early months of summer, we start to see some of the earliest flower blooms. Bees and butterflies are also very active at this time.

Two of the earliest events take place in August. The first of these is a migration of whales and dolphins after they return from the Southern Ocean to the waters around Antarctica. The next is an explosion of wildflowers. Autumn is also known as the fall , begins when the day and night are the same lengths again. During autumn, leaves change color and fall from the trees.

Birds of prey, such as the eagles and hawks, and raptors, such as hawks and owls, are great divers, diving for small fish or shellfish from shallow waters. In the Northern Hemisphere, this transition comes about in September, around the first week in September. Tilted Earth: Earth has seasons because its axis is tilted. Due to this tilt, the North pole leans towards the sun for half the year and away from the sun for the rest. What is an axis? Earth rotates around an imaginary line called an axis.

It is tilted at an angle of Also Read: Earth Facts. And at the same time, it is opposite in the Southern Hemisphere when it is tilted away from the sun. It gets less intense sunlight for fewer hours of the day which makes the Southern Hemisphere cooler weather i. The northern and southern hemispheres always have opposite seasons. If there is winter in the Northern Hemisphere then it would be summer in the Southern Hemisphere. Also Read: Layers of the Atmosphere.

Solstices occur twice a year when the sun is at its greatest distance from the equator. In other words, the days that the Earth is most tilted toward the sun are called Solstices. Did you know? In the southern hemisphere, the winter solstice falls in June but in the northern hemisphere, the winter solstice falls in December.

It comes on around June Summer solstice is the longest day of the year. The sun is highest in the sky on the summer solstice. The spring equinox is called the Vernal Equinox. It is the first day of the spring season. Spring equinox is near March It is true that Earth's orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the Sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the Sun and summer when it is farthest away!

Compared with how far away the Sun is, this change in Earth's distance throughout the year does not make much difference to our weather. Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom. That is why we have day and night, and why every part of Earth's surface gets some of each.
