When Earth's crust and upper mantle act together mechanically, they are called the _. The molten lower mantle is called the _. The current best hypothesis to explain the origin of the Moon is called the _ hypothesis. What common molecule dominates the atmospheric compositions of Venus and Mars? _ Earth's atmosphere is transparent primarily to _ and _ regions of the electromagnetic spectrum.Explanation / Answer
1 .volcanic rocks are igneous rocks. When the rocks undergo physical altration dueo to heat and pressure, they become metamorfic rocks. When rocs form agglomaration of other rocks called sedimentary rocks.
Igneous rocks: these are formed by cooling and solidification of magma
metamorphic rocks: these are formed when pre-existing rocks have been changed texture and composition by increased in pressure and temperature.
sedimentary rocks: these are formed by consolidation and cementation of sedimentary deposits under water.
2. The two planets being that are closest being identical are venus and earth. These two planets have more or less same size and shape.
3. Weathering is the only geological process that occurs everywhere on solar system.
4. When crust and upper mantle mechanically, they together called lithosphere. The molten llower mantle is called mesosphere.
5. The current best hypothessis for origin of earth is gain-impact hypothesisThis hypothesis suggests a body called Theia of Mars size impacted Earth, creating a large debris ring around Earth, which then accreted to form the Moon.
6. The common moleclues of the Venus and Mars are carbon dioxide, argon, nitrogen, water, methene, and hydrogen.
7. Earh' atmosphere transparent primarily to visible and radiowave regions of electromagnetic spectrum.
