Plate Tectonics
Plate tectonics are underground sections of the earth that devide the world into puzzle piece like parts. There are three types of plate tectonic boundries, divergent, convergent, and transform. Convergent boundries move towards each other, while divergent boundries move away from each other, and transform boundries move along each other. The theory of plate tectonics was made by a scientist named Alfred Wegener. Alfred Wegener was shamed in his time for his "crazy" ideas. Later scienctists realized that his ideas had some merit and realized that his theory could be plausable. Tectonic plates are the reason for a lot of natural occurences, like earth quakes, volcanoes, tsunamis and more which greatly effects daily life.

Layers of the earth
Layers of the Earth
There are 4 main layers of the earth crust, mantle, inner core, and outer core. The first main layer is the crust. The crust is the thinnest layer, the two types of crust are oceanic and continental. The second main layer is the mantle. It is the thickest layer, it is solid, and makes up 84% of the earth's volume. The inner core is the third main layer is made up of liquid iron and nickel making it liquid the outer core can reach temperatures up to 5,500 Celsuis. The inner core is the last main layer. It is made up of mostly iron, the temperature is 5,200 Celsuis, and even though it is way above the melting point for iron it is solid. The layers of the connection are everyday lives because they help scientists because the crust makes up the ground we walk on and they help with seismic waves. As the layers changed over time they became hotter and stronger. As the crust changes the earth's surface changes as well. The layers over time change many things about the earth but not all these changes are permanent.

Rock Cycle Summarization
The main rocks are known as Igneous,Sedimentary, and Metamorphic. These rocks change shape into each other in different ways. For instense,sediment forms into sedimentary rock by compaction and cemetation, Sedimentary rock forms back to sediment by weathering and erosion, sedimentary rock forms into metamorphic rock by heat and pressure, metamorphic turns into magma by melting, magma turns into igenous rock by cooling, igneous turns into sediment by weathering and erosion, and the process repeats and repeats. This process is called the Rock Cycle. The forces on the Earth's surface that is deep into the Earth drive the Rock Cycle, otherwise known as convection currents.

Rock Cycle
The rock cycle relates to our everyday life because without the Rock Cycle we wouldn't have different types of landforms that form from Rocks like for example, the mountains and canyons. And without mountains and canyons we wouldn't have beautiful tall mountains like the Himalayns, and we also wouldn't know the science behind rocks and our knowlodge on geology would be limited, since the Rock Cycle gives us more knowlodge about geology. Without the Rock cycle we wouldn't have different types of Rocks which form from the Rock Cycle. Another reason why the rock cycle relates and impacts our entire life because without it then weathering and erosion would end since it's the only process that is apart of the Rock Cycle can only exsit because of it.
How this relates to our everday life
The Rock Cycle relates to change because the rocks form into different types of rocks by physcial change. For example, weathering, melting,cooling, compaction, erosion, and more. All rocks can change or transform into any rock by going through one or more of thesesteps/ processes. The Rock Cycle changes by Earth's heat. Another way the Rock Cycle can change is how molecules can change or form into a rock which would appear in a common shape.

Minerals
Minerals are naturally occuring inorganic solids that have an orderly internal structure and a fixed chemical composition. There are many different ways to tell what mineral one because they all have different properties to them. People find out what kind of mineral one is by finding its luster, hardness, density, streak, and acid reaction.
