Quizlet: At what type of boundary are mid-ocean Ridges?
Oceanic ridges and large mountain belts are formed at convergent borders. Divergent plate boundaries are where you will find Mid-Ocean Ridges.
What are the two processes that occur at mid-ocean ridges?
There are two main processes that are responsible for spreading at mid-ocean islands ridges. However, it is not clear which one is more dominant. Ridge-push is when the weight of a ridge pushes other tectonic plates away from the edge, often towards a subduction area.
Which of the following increases with distance from a mid-ocean ridges?
The age, density and thickness of the oceanic crust increase with increasing distance from the midocean ridge. The magnetism of mid-ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
Which feature of Earth is created at mid-ocean ridges quizlet?
Seafloor spread is a process at mid-ocean Ridges where new oceanic crust forms through volcanic activity. The crust then slowly moves away from the edge. Seafloor spreading is a key component of the theory behind plate tectonics.
What was Harry Hess theory of seafloor spreading?
Hess believed that the oceans would grow from their centers, with molten material or basalt rising from the Earth’s crust along the mid-ocean ridges. This created new seafloor, which spread out from the ridge in both direction.
How do mid ocean ridges form quizlet?
How do mid-ocean Ridges form? Convection currents deep below the ocean bring molten material to the top of the mantle. This material rises from faults (cracks), between oceanic plates moving away from each other. This material fills cracks and hardens to form new crust.
Which feature of Earth is created at mid ocean ridges Brainly?
The correct answer is: underwater mountain ranges.
Which statement best describes the theory of plate tectonics?
Answer : The best statement about plate tectonics theory is that some sections of Earth’s continentals are in slow continuous movement.
Which statement explains why tectonic plates move?
Graviton is the main driver of plate tectonics. Graviton is the main driving force behind plate tectonics. When a plate covered with oceanic and lithosphere meets another, the dense oceanic layer sinks into the mantle. Subduction is the name of this process.
Which plate does not appear in both hemispheres?
Which type of fault is a transform boundary?
A transform fault is a case in point of a strike slip fault, which also forms a plate boundary.
What was the main reason Wegener’s continental drift hypothesis was rejected?
Wegener’s hypothesis was rejected because it suggested no mechanism to move the continents. Wegener believed that the Earth’s spin would cause continents to move. But geologists know that rocks are too strong to support this claim.
What can you say about the continents before Pangea split?
About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Laurasia was formed from the current continents of North America, Europe, Asia and North America (Greenland). Gondwanaland was formed from the current continents of Antarctica (Australia), South America, and South America.
