What else can I help you with?
What are 3 things of evidence that scientists have that prove the ocean is spreading?
1) seafloor spreading 2) continental drift 3 i only found 2
Do tides only occur in the oceans?
Yes.
How does magma help seafloor spreading?
Magma plays a crucial role in seafloor spreading as it rises from the mantle at mid-ocean ridges, where tectonic plates are diverging. When magma reaches the ocean floor, it cools and solidifies, forming new oceanic crust. This process not only creates new seafloor but also pushes older crust away from the ridge, facilitating the movement of tectonic plates. As a result, seafloor spreading continuously reshapes the ocean floor and contributes to geological activity.
How does seafloor spreading affect us?
seafloor spreading affects us with help from continental drift. seafloor spreading creates new seafloors, but moves the continents a few centimeters apart from each other every year. in many years, pangaea will become aeagnap, because the continents will become one big land again, but backwards, and will damage the faults and the only land we have severely.
Algae can survive on the seafloor only in what?
Algae can survive on the seafloor only in shallow waters where there is enough light for photosynthesis to occur. Deeper in the ocean, there is insufficient light for algae to thrive.
Algae can survive on the seafloor only in?
Algae can survive on the seafloor only in shallow waters where there is enough sunlight for photosynthesis to occur. Deep sea areas lack sufficient light for algae to survive.
Why is the seafloor young?
The seafloor is continuously being created at mid-ocean ridges through seafloor spreading, where tectonic plates move apart and magma rises from the mantle to create new oceanic crust. As a result, the oldest seafloor is only about 200 million years old, much younger than continental crust which can be billions of years old.
When Seafloor spreading is occurring at the boundary between the?
When seafloor spreading occurs at the boundary between tectonic plates, it typically takes place at mid-ocean ridges, where two oceanic plates diverge. As the plates pull apart, magma rises from the mantle to fill the gap, solidifying to form new oceanic crust. This process not only creates new seafloor but also contributes to the age progression of the ocean floor, with younger rocks located closer to the ridge and older rocks further away. Seafloor spreading is a key mechanism of plate tectonics and plays a significant role in shaping ocean basins.
What is seafloor spreading that ''helps'' the theory of continental drift?
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
How did Harry Hess hypothesis explain seafloor spreading?
Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the ridge.
What geologic processes and or phenomena is not found at transform plate boundaries?
At transform plate boundaries, processes like subduction and seafloor spreading do not occur. Instead, these boundaries are characterized by the sliding past of two tectonic plates horizontally. There is no creation or destruction of crust at transform boundaries, only sideways movement.
How did Harry Hess discover seafloor spreading?
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.
