What have I learned?
Rocks
Rock commonly means the little things form large rocks when the large rock gets hit, there are some little things that fall down.
-
Most rocks are block or oval, their surface is rough or smooth the texture is firm and crisp.
metamorphic rocks
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
-
Sedimentary rocks
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation.
-
Igneous rocks
The igneous rocks that commely are basalt, andesite and granite.
-
-
layers of the earth
-
outer core
It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances.
-
The crust
-
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust.
-
inner core
The inner core is more than 5,000 kilometers below the earth's surface.
-
Tectonic Boundaries
In the theory of plate tectonics, a boundary between two or more plates. The plates can be moving toward each other (at convergent plate boundaries),
Convergent Boundaries
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into mountain ranges or one of the plates may bend down into a deep seafloor trench.
Divergent Boundaries
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create a new oceanic crust.
Transform Boundaries
Transform boundaries are places where plates slide sideways past each other. At transform boundaries the lithosphere is neither created nor destroyed.
Many transform boundaries are found on the seafloor, where they connect segments of diverging mid-ocean ridges.

Atmosphere
troposphere
-
-
Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
stratosphere
The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere.
-
thermosphere
The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.
Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.
