It is pretty amazing how much we know about the inside of the Earth, given that we can only directly observe a small part of it. When we learn about the layers of the Earth, we learn that the crust is very thin, but that is only on the scale of the rest of the Earth. Relative...

Layers based on chemical composition are the core, mantle and crust. According to mechanical properties, Earth's layers are thelithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core, according toPhys.org. We will explore each of Earth's layers in...

Snowflakes(雪花) begin inside the clouds. The snowflake crystals form within storm clouds high above the earth. There are manry differem cloud layers (层) in the upper air. You can see them floating freely,changing shzpe.The air around our plenet is alweys moving. The higher the air is...
but they are not sure exactly what causes the great heat.Some geologists have thought that the heat is caused by the great pressure of the earth’s outer layers.Or the heat may be left from the time when the earth was formed.During the last sixty years scientists have learned about ...
Earth's interior is split into four layers — the crust, the mantle, the outer (liquid) core, and the inner (solid) core. Near the bottom of the mantle are two immense formations, discovered in the 1980s by studying seismic waves sweeping through the planet...
