PPT-Notes on the Ocean Floor

Ocean Floor Features When we look across the ocean we see miles and miles of water However if we were to look under all this water we would see many geological features that look very similar to those found on land.

What does the ocean provide for us?. What does the Ocean floor look Like and how do we know this?. How much of earth is covered by the oceans?. - Almost 71% of the earth’s surface is covered by our ocean.. 20.2. Continental Margins. The line that divides the continental crust from the oceanic crust is not always obvious.. Shorelines are not the true boundaries between the ocean floor and continents.. The real boundary lies offshore beneath the ocean and thick sediments.. Plate tectonics review. Earth’s lithosphere is divided into large tectonic plates. They are constantly in very slow, motion.. Plate tectonics review. ____________ pushes the tectonic plates apart in sea floor spreading. This causes the motion of the plates..
