A shake is a basic wooden shingle made from split logs. Shakes have traditionally been used for roofing and siding applications around the world. Higher-grade shakes are typically used for roofing purposes, while the lower grades are used for siding.
Since Earth and Venus have similar size and density, scientists assume that Venus has a similar internal structure to Venus, with a core, mantle, and crust. The interior of Venus is probably at least partially liquid. One big difference between Earth and Venus; however, is the fact that Venus has no plate tectonics. This is probably because the surface and atmosphere of Venus are so dry and hot. This reduces the amount of heat lost from the interior of the planet, and prevents it from cooling.
What is Saturn made of? Saturn is not solid like Earth, but is instead a giant gas planet. It is made up of 94% hydrogen, 6% helium and small amounts of methane and ammonia. Hydrogen and helium are what most stars are made of. It is thought that there might be a molten, rocky core about the size of Earth deep within Saturn.
