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.

As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles.The liquid âfreezesâ to form volcanic glass. Chemically lava is made of the elements silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, potassium, phosphorus, and titanium (plus other elements in very small concentrations.s magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases.
