How boundaries move, the types of boundaries, and what they are!
The plates are separate sections of the lithosphere. The plates fit together along the cracks in the lithosphere. The plates move by convection currents in the mantle. During subduction, gravity pulls one edge of a plate down into the mantle. The rest of the plate also moves. There is the theory of plate tectonics state that there used to be a super continent Pangaea existed. It also states that pieces of the lithosphere are in slow, constant motion. The types of boundaries are divergent,convergent, and transform boundaries.
Volcanoes
Volcanoes lava destroys and adds to the land.
Earthquakes
Earthquakes rip apart the land and destroy every building in its path.
Tsunami
Tsunami washes and destroys habitats and cities.
Erosion at its Finest
What it is, the types of erosion, and what type changes the Earths surface the most
Erosion is a destructive force that is constantly breaking up and wearing away, or weathering, all rocks on Earths surface. The types of erosion are wind, water, and ice. Water causes the most damage to the Earth's surface because it can use tsunamis to tear away a large around of rock. It also uses other destructive forces it can use.
What I did over spring break!
I played a lot of Diablo 3 which is a video game made by the same people who made World of Warcraft! I played it mainly after Tuesday because the new expansion for it came out! I mainly played with my friends and we had a blast! We also stayed up very late.

Ancient Relics of The Past
The Law of Superposition
The law of superposition is a law of observations on natural history.
How can fossils tell us about the history of the Earth?
They can show the animals millions of years old and how they evolved.
Are all fossils the same?
No, fossils may be made of bones, but they are formed differently and are different ages.
Rock'n in the Deep
Igneous rocks
Igneous rocks form when magma or lava cools and hardens.
Sedimentary rocks
Forms when pieces of rock are and cemented together.
Metamorphic rocks
Forms from other rocks that are changed by heat and pressure.
The Rock cycle.
So the rock cycle starts as sediment which is sent away and becomes sedimentary rock. Here it is either erodes and starts at the beginning,or even could melt, or moves on to metamorphic by heat and pressure. At metamorphic, it either erodes again or it melts into magma and lava. Volcanic activity could turn into igneous rock. Igneous rock could change into metamorphic rock by heat and pressure or gets eroded into sediment.
How we identify minerals and the two ways minerals form.
We can identify minerals by their crystal structure, their color, the properties it is made of, streak and luster, density, and hardness all are what we need to test to identify a mineral. Minerals can form from hot magma cooling inside the crust to form crystals and when elements dissolve in water they leave a solution that later forms minerals.
What I loved best.
I loved learning on how earthquakes change the surface forever.
