What is snow? Weather – Earth science

If it's colder, rain may fall as snow. About two and a half billion years ago, the Earth finally cooled down enough for it to snow for the first time. Most of the time since then, the Earth has been warm enough that it didn't snow at all. But from time to time, the Earth becomes cooler, entering [...]

This is why it's hotter in summer and colder in winter. The reason it is sometimes winter and sometimes summer is that the Earth spins on a slightly tilted axis. You can see the red axis in the picture here (though really there is no axis to see; it's a direction, not a real stick). [...]

Still in their coats on a sunny day(Thanks to [seattle + beyond]) To see what a difference it makes whether sunlight hits the Earth directly or at an angle, just think about a sunny day in summer and a sunny day in winter. In summer, when the sun is out it soon gets very hot. Even cloudy days, when the sunlight has to come [...]

This is what the planet Venus looks like from space. Venus is the second planet away from our Sun - Mercury is closer to the Sun, and then the Earth is a little farther from the Sun. Like the Earth, Venus probably formed about four and a half billion years ago, out of space dust in the same nebula. Venus is [...]

Earth from space: How old is the Earth? When did the Earth form? Like Mercury and Venus and the other planets that go around the Sun, the Earth probably formed a little more than four and a half billion years ago. (That's about 4,600,000,000 years ago.) What's the sun made of? How do planets form? All our physics articles What [...]
