Welcome to the Earth section! SOURCES: WIKIPEDIA,
Earth is the third planet from the Sun and the only place we know of where life exists. One big reason life can exist here is that Earth is an “ocean world.” This means it has a lot of water on its surface, and it is the only planet in our Solar System with liquid water that life can use. Most of Earth’s water is in the oceans, which cover about 71% of the planet’s surface. The rest, about 29%, is land. Most of this land is grouped into large continents, like North America, Africa, and Asia, which are mostly humid and covered with plants. Even the icy parts at the North and South Poles hold more water in their ice sheets than all of the lakes, rivers, and underground water combined.[23] Earth’s outer layer, called the crust, is made of big pieces called tectonic plates that slowly move around. When these plates push against each other, they can create mountains, volcanoes, and earthquakes. You can think of it like giant puzzle pieces slowly sliding and bumping into each other. Deep inside Earth, there is a liquid outer core. This spinning liquid creates a magnetic field around the planet, called a magnetosphere. The magnetosphere works like a protective shield, keeping most of the dangerous solar winds and cosmic radiation from reaching the surface, which helps life survive
Earth has a atmosphere, a layer of gases that is around the planet Earth, This atmosphere is important because it keeps Earth’s surface just rigt for life.
Most of the atmosphere is made of nitrogen and oxygen, the gases we breathe. There is also water vapor in the air, which forms clouds that cover much of the planet
