What else can I help you with?
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.
What is the system of cracks that form where the seafloor is spreading apart called?
The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
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.
Mineral rich water heated by newly formed oceanic crust escape through cracks in the floor called?
Hydrothermal vents.
What is you it called when volcanic activity occurs along mid-ocean ridge in large cracks?
Volcanic activity along mid-ocean ridges in large cracks is called seafloor spreading. This process occurs as magma rises to the surface through these cracks, creating new oceanic crust as the tectonic plates move apart.
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
Why are roads covered in cracks and potholes in the winter time?
Roads can develop cracks and potholes in winter due to the cycle of freezing and thawing. When water seeps into cracks in the road surface and freezes, it expands, causing the pavement to crack. As vehicles drive over these weakened areas, the pavement can break apart, forming potholes. Additionally, the use of road salt and other de-icing chemicals can further deteriorate the road surface.
Is cracks forming a bolder weathering?
Yes, cracks forming in a boulder are a type of physical weathering. As water seeps into the cracks and freezes, it expands, causing the rock to break apart gradually. Over time, this process breaks down the boulder into smaller pieces.
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.
What forms in cracks or along faults?
Minerals can precipitate within cracks or faults, forming veins. Water can also accumulate in these features, leading to the formation of geodes or stalactites/stalagmites. Additionally, sediments may accumulate in cracks and faults, forming breccia or fault gouge.
What is the system of cracks that form where the seafloor is spreading apart called?
The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
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!
What might cause a bulge in the slope of a volcano?
the magma growing in size and large cracks forming
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 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
