Good Morning Students! Today we are going to learn about the parts of the ocean floor.
Parts of the ocean floor!
Parts of the ocean floor: ~Continental Shelf: An area off the shore with a shallow depth. ~ Continental Slope:A steep slope from the continental shelf to the continental rise. ~Trench: A deep narrow dip in the ocean floor. ~Rift Valley: A valley created by tectonic plates. ~Wave Trough and Crest: Trough is the bottom part and crest is the top part of a wave.
We are only learning about some parts of the ocean floor because we have more to learn about so here are the ones we are going to learn about and read!
Tides and Currents! Tides happen 4 times a day! There is two high tides and two low tides! Tides are caused by the gravatational pull of the moon and the earth. Currents: Currents are a body of water moving in a direction. Currents are caused by wind, breacking wave, or any eruption. Our current is the gulf stream!
Welcome students today on our next lesson we are learning about tides and currents!
Erosion is when the land mass gets broken down. Deposition is when the land mass that is broken down gets carried away and creates new landforms! Like the Grand Canyon! Weathering: There are two types of weathering chemical and mechanical!A constructive force is something that build up or creates a new land mass! Like landslides! A destructive force is something that breaks down land forms! Like a tornado!
Today we took a feild trip to learn about weathering erosion and depositon!
Pollution: Is something that harms our enviorment it can be physical or chemical. Conservation: is something that is helpful to our enviorment it can be physical or chemical.
