Continental Drift Continental drift is the moving continents. Before we had earth visual that called Pangaea. Pangaea mean whole land. Then locations of continent is changed by continental drift.
Continental Drift The person who invent this theory is Alfred Wegener (1915) According to Wikipedia resource the theory was: “All continent were joined in one giant continent then replace the location and moved away from each other.
Continental Drift Evidence : People found same type of animals, rocks, fossils and mountain range in two or more different continents.
The Ring of FireEarth Science – Lithosphere Layer
The Ring of Fire is the ring of active and sleepy volcanoes. Ex: Pacific ring of fire. A lot of volcanoes in coast of continents around the pacific ocean. Boundary type is convergent plate boundary. It is important because arc and active volcanoes appear by one tectonic plate goes another.
Mountain Building Earth Science – Lithosphere Layer
Mountain Building• Mountains formed by many different ways.Crashing two tectonic plates, lava came because ofvolcanoes and turn to sold that make mountains.• Types of mountains: Folded, Dome, Fault-Blockand Horst & Grabens.• Folded mountains are created by tectonic platespushing each other.Ex: Himalayan Mountains in Asia, the Alps in Europethe Andes in South America, the Rockies in North America, theUrals in Russia
Mountain Building Dome mountains are created by melted of rock getting up from earth’s crust. Fault-Block mountains are created by cracking earth’s crust and appeared block moving up or down. Ex: The Sierra Nevada mountains in North America, the Harz Mountains in Germany.
Mountain Building Horst & Grabens mountains are formed from extension of earth’s crust. In this type of mountain broken block moving up and down.
