Explain why it is important to study geology How do we divide up what is inside the earth? How are the layers divided up according to composition? (draw picture and describe) How are the layers divided up according to how they behave (draw a picture) o o What rock type makes up continental crust? . What rock type makes up oceanic crust? (you will see this over and over again) How do oceanic crust and continental crust differ? (which is thicker, which is denser) How do rocks form? What is the rock cycle? Be able to briefly explain orders in which the rocks may move through the rock cycle. How did our solar system form? . . o Which planets are considered the terrestrial planets o Which are the larger gaseous planets o List the planets in order

It is very essential to study the geology of the earth and its formation, its erosion and deposition and also study how the rocks got arranged in there present forms and also essential to understand the basic evolution of the earth as a distinct terrestrial planet.

The earth's four layers divided into distinct boundaries based on the rock matter from below and its composition that is shaped by the endogenetic and exogenetic forces from above and below.

The lithosphere of the lithosphere is composed of thin sheets of rocks that are known as plates and composed of silica, and aluminum layers. Oceanic crust composed of 5-meter thick basalt, diabase, and gabbro rocks.

Below this layer is the Upper manure; known as Asthenosphere or the magma or lava or basaltic layer. Having a depth of 2900 kilometers this layer is of high density and has a high mass and volume.

A thick layer of liquid composed mostly of magnesium and silicon and other elements that accumulate with high pressure to form buring of overriding slabs of rock. The lower mantle is composed of iron and heavy elements. Below which is the core which has outer and inner components like the nickel.

The rock cycle is the cycle that recycles the rocks through the internal structure of the earth to balance the isostatic equilibrium of the landmass on the surface. Like basaltic rock get sedimentary get metamorphosed to form metamorphic rock and further get converted to igneous rocks.

Mercury, Venus, Earth, Mars are considered terrestrial or rock plants as compared to the giants like the Jupiter, Saturn, Uranus and Neptune all in order.
