Layers of the Earth

What is the thickest layer of the Earth? The mantle
What layer of the earth is the most dense? The inner core
What layer is a part of the Lithosphere? The crust
What layer of the Earth is the least dense? The crust
What is the top layer of the Earth? The crust
What is the bottom layer of the Earth? The inner core
Where are the convection currents located? Asthenosphere
What is the most upper layer of the mantle and the crust? Lithosphere
What are the two types of crust? Continental and Oceanic
Can every rock turn into every type of rock? Yes, but it depends on its formation
What are the building blocks of rocks? Minerals
Are minerals rocks? NO
What make the sediments in sedimentary rocks? Weathering and erosion
What do weathering and erosion cause? Sediments which are then deposited and undergo compaction
What is the final step to make a sedimentary rock? Cementation
Where are sedimentary rocks found? In the crust in the Lithosphere
What rocks are formed from heat and pressure? Metamorphic Rocks
How are metamorphic rocks formed? At plate boundaries where they collide and subduct.
How are igneous rocks formed? Melting and cooling (makes hardening)
Where are igneous rocks formed? Asthenosphere and Lithosphere
How do igneous rocks make it to the surface? Tectonic plate movements
What are the three boundary called? Convergent, Divergent, and Transform
What do convergent oceanic-continental or oceanic-oceanic plates do? Collide, and the denser the plate will subduct and create a trench at the top where the plates collide, or
What do convergent continental plates do? The collide, push up, and make mountains.
What do divergent oceanic-oceanic plates do? They will cause sea-floor spreading. Lava comes up between the two parts.
What happens when the lava cools after sea-floor spreading? It hardens to create new crust and forms a mountain ridge under the water.
Continental-continental divergent boundaries go through what process? The ground will form rifts, tear/crack, or valley as it pulls apart.
What happens with transform boundaries? They slide past one another and cause fault lines and earthquakes.
What are 6 important tectonic plate names? African, Antarctic, Eurasian, Indo-Australian, North American and South American
