What is likely to occur at a plate boundary where the oceanic crust collides with the continental crust?
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
Mineral rich water heated by newly formed oceanic crust escape through cracks in the floor called?
Hydrothermal vents.
Mineral rich water heated by newly formed oceanic crust escapes through cracks in the ocean floor called?
Th water escapes through cracks in the ocean floor called hydrothermal vents.

Why do mountains often occur thousands of km long?
They were pushed up from the earth underneath in the ages of the Continental drift. Two masses of land colliding together will make for extra terrain to seep up through the cracks forming mountains
What is a continental arc system?
These arc systems form at collision plate margins where an oceanic plate is being subducted under a continental plate. As the oceanic plate melts, the magma rises and finds cracks in the continental plate above and creates volcanoes. These volcanoes occur all the way along this plate margin. For example the cascade volcanic arc on the north west coast of USA.
What are plate boundaries in volcanoes?
Volcanoes are caused by convergent plate boundaries. As the oceanic and continental plate collide into each other, subduction occurs: the oceanic plate is denser so it goes under. As it gets more below the earth's surface, the temperature gets higher. Soon, it melts into magma and turns less dense, then rises up through the cracks of the continental plate above. This then causes volcanoes to form on top of the continental plate. .
What things have proved continental drift has occurred?
cracks and earthquakes

What might cause a bulge in the slope of a volcano?
the magma growing in size and large cracks forming
Do these plates move?
Dr. Alfred Wegener proposed the continental drift theory which states that the lithosphere drifts apart because of the gravitational pull of the moon. Harold Jeffreys contradicted the idea. He said that if Dr. Wegener's proposal is true, then the gravitational pull of the moon could stop the Earth from moving. The Earth is still moving today. There is another theory called Seafloor Spreading which states that the oceanic crust moves apart forming cracks. The magma goes through these cracks and up until it cools. When it cools it sinks and goes through the cracks. This is why our seafloor is very young. The sea floor is recycled. The most acceptable theory is the Plate Tectonics theory which is the combination of Continental Drift Theory and Sea floor Spreading. I hope this helped you a lot. This is a stranger helping a stranger. I hope this will strengthen our mutual relationship. Thank you!

Why was the second continental congress more like a goverment than the first continental congress?
be cuz they taxed all those bitches as cracks suck mi dick
