Inside the earth
The Earths core is a ball of hot liquid magma and iron, that is the core of our earth. The mantle on the other hand help provide the earth with its mass, and that mass helps with our gravity and helps balance out the gravitational pull of both the moon and the earth. If the pull of the moon is greater then we can experience high tide in our oceans, because the moon also has mass, but the earths mass help keep things from floating away.The mantal is about 6 miles.the matle is to divide the inner mantal and the outer mantal.the crust is the earths hardest shell, that is the surface which we live on.

The seasonal chage of the earth


 When the Northern Hemisphere is tilted toward the sun, we experience summer. When the Northern Hemisphere is tilted away from the sun, we experience winter.During winter in the Northern Hemisphere, the sun’s light has to travel further through the atmosphere than it does during summer. The atmosphere uses some of the heat energy carried by the light. That means that by the time the light reaches the ground, there is less heat energy available to keep things warm.P eople in the Northern Hemisphere have winter, those in the Southern Hemisphere have summer.
