What did sea floor spreading do to Pangaea?
Sea floor spreading contributed to the breakup of Pangaea by creating new oceanic crust at mid-ocean ridges, causing the continents to drift apart. This process resulted in the formation of the Atlantic Ocean and the separation of the once-contiguous landmass Pangaea into multiple continents.
How sea-floor spreading provides a way for continents to move Explain?
Sea-floor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing the existing crust apart. As the crust spreads, it carries the continents on tectonic plates with it, causing the continents to move. This movement is called plate tectonics, and it is responsible for the shifting of continents over geological time scales.
Why does oceanic crust get older as you get closer to continents?
The basalts of the ocean floors are created at the mid-ocean ridges and moves away from these ridges as new crust is created. thus as sea floor spreading occurs the older rock gets pushed away from the ridge towards the continents and the younger rock comes up beside the ridge. good example is the Atlantic ocean
Continents and the ocean floor are part of earths solid rocky surface called?
crust
Does the ocean floor have features that are the same as features found on continents?
Yes, the ocean floor has features such as mountains, valleys, ridges, and plains that are similar to those found on continents. These features are formed by processes like tectonic activity, volcanic eruptions, and erosion. Additionally, both the ocean floor and continents have ecosystems that support various marine and terrestrial organisms.
What process helps explain how continents drifts?
Ocean-floor spreading.
What is it called when the sea floor spreads out from both sides of a mid ocean ridge and moves towards continents?
sea floor spreading or divergent boudary
What is composed of the continents and the oceans floor?
Earth's crust is composed of the continents and the ocean floor.
Can plated carry continents or parts of the ocean floor but not both?
Tectonic Plates can't carry both ocean floor and continents on the same plate.
What is things rest upon crustal plates?
The continents and the ocean floor rest upon the plates.
Do continents reach the bottom of the ocean?
They do touch the ocean floor. they're like a giant mound, and the beaches flow into the water.
What is the surface of the planet that forms the continents and ocean floor?
The crust.
Why are basalt and granite important igneous rock?
As it turns out, most of the ocean floor is basalt, and most of the continents are granite.
What did sea floor spreading do to Pangaea?
Sea floor spreading contributed to the breakup of Pangaea by creating new oceanic crust at mid-ocean ridges, causing the continents to drift apart. This process resulted in the formation of the Atlantic Ocean and the separation of the once-contiguous landmass Pangaea into multiple continents.
Why is the Atlantic Ocean is spreading?
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
How do scientist know that the continents are moving?
the ocean sea floor is spreading
What are the steps in the process of the sea-floor spreading?
In sea-floor spreading,the sea floor spreads apart along both sides of the mid-ocean ridge as a new crust is added.As a result,the ocean floors move like conveyor belts,carrying the continents along with them.
