The outside of the earth is a crust of rock that is about 10 to 30 miles thick. When we go down into this crust. we find that it begins to get hotter and hotter.
For about every 40 meters we go down, the temperature grows one degree higher. At two miles below the surface of the earth, the temperature is high enough to boil water! If it were possible to dig down 30 miles, the temperature would be about 1,200 degrees Centigrade. This is hot enough to melt rocks. At the center of the earth, scientists believe the temperature to be about 5,500 degrees Centigrade.
The crust of the earth has two layers. The upper layer, which makes the continents, is made up of granite. Under the layer of granite is a thick layer of very hard black rock called “basalt”. This layer supports the continents and forms the basins that hold the oceans. At the centre of the earth, it is believed that there is a huge ball of molten iron, with a diameter of about 4,000 miles.
How did the center of the earth get to be this way? According to most scientific theories, the earth and sun were once related in some way. Most scientists believe that the earth was once a hot, whirling mass of gas, liquid, or solid that began its regular trips around the sun. As the years went by, it slowly cooled and the large mass grew smaller. As it whirled, ii slowly took a ball-like shape. It was red—hot and held in its path by the attraction of the sun.
As the earth cooled, a hard crust formed on the surface. Nobody knows how long it took for the cru5t to form. But underneath that crust there remained the hot central core of the earth, and it is still there today.
Why Is The Earth Still Hot Inside?
The Earth is still so hot inside in large part because its surface is too small, relative to its volume, for this heat to escape
Earth’s interior is hot, and that’s because it’s created by a Red-Hot Redstone Volcano! If you’ve ever wondered why Earth is so hot, this is the answer you’ve been looking for.
What is the hottest layer of the Earth?
Which is the thickest layer?
Which city is in the middle of the world?
Which city is the middle of the world? If you think it’s either: New York or London, you’re wrong. According to the US Census Bureau, the middle of the world is actually located in the city of Visalia, California. A lot of people think that because Las Vegas lies in the middle of the US, that’s why it’s thought of as the middle of the world. However, this is not true; according to a map of the US, Las Vegas does not lie in the center, but off to the east.
