Explain what plate tectonics and ocean trenches have in common?
Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)
What major ocean floor did oceanographers discover after World War 2?
The mid-ocean ridges were discovered in the Atlantic Ocean after World War II. These undersea mountain ranges mark places where tectonic plates are moving apart, allowing magma to rise from below the Earth's crust. This discovery fundamentally changed our understanding of the structure of the ocean floor and led to the development of the theory of plate tectonics.
What is 170 degrees celsius in gas mark?
170 degrees Celsius is equivalent to gas mark 3.
How do scientist know where plate boundaries are?
Scientists use a combination of techniques such as studying earthquake patterns, volcanic activity, topography features, and the distribution of rock types to determine where plate boundaries are located. They also use high-resolution mapping technologies like satellite imagery and GPS data to track the movements of the Earth's tectonic plates.
What happens to the old crust as new crust forms?
The older crust is pushed away from the spreading center as new crust forms. This process creates a conveyor belt-like movement of crustal material away from the mid-ocean ridges where new crust is being generated. Over time, the older crust will cool, thicken, and become denser as it moves farther away from the spreading center.
