The type of collision that occurs when two lithospheric plates converge is determined primarily by plate?
the convergent boundry type is determined by the types of plates. There are Continent - continent plates converging this forms mountains. Then there a Oceanic crust and continental crust colisions which form subduction zones and volcanic activity on the continents side. Lastly there are Ocean - Ocean plate collisions where the hotter and younger ocean floor obducts onto the older floor.
When India and Australia move in different directions what type of plate boundary will form between them?
A divergent boundry will form beetween them.
Is the ocean floor a good place for fossils to form?
A lot of shells of marine organisms wind up on the ocean floor. Bones do not last on the ocean floor, they get eaten. But shells can last.
What plate boundary does a deep ocean trench form on?
spreading
Can both volcanoes and earthquakes form on the ocean floor?
yes

What causes material to form at a mid-ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
What theories were combined to form the theory of plate tectonics?
the continental drift and the ocean-floor spreading
What cause new material to form at a mid ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
In which location would an ocean ridge?
The mid-ocean ridge is almost in all of the oceans
The youngest rocks on the ocean floor are located?
The youngest part of the ocean floor is found at conservative plate boundaries where oceanic crust is pulled apart and magma rises from the mantle to form new oceanic crust.
When India and Australia move in different directions what type of plate boundary will form between them?
A divergent boundry will form beetween them.
How does new ocean floor form?
Sea Floor Spreading!
How does new mid-ocean ridge form?
a mid-ocean ridje is an undersea mountain chain where new ocean floor is produced;a divergent plate boundary under the ocean.
What are the 4 steps of seafloor spreading?
I'm not that sure since I am doing a science assignment on seafloor spreading but, I think I've got a pretty good grasp on 5 stepsMagma pushes up through the Earth's mantle and breaks through the crust.Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.New ocean floor pushes the old floor away from the mid-ocean ridgeThe old floor then pushes the continents away from the ridgeLastly, the old ocean floor is forced under the continental plate, and melts back into magma.I'm not that sure but, I think I've got a pretty good grasp on 5 stepsMagma pushes up through the Earth's mantle and breaks through the crust.Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.New ocean floor pushes the old floor away from the mid-ocean ridgeThe old floor then pushes the continents away from the ridgeLastly, the old ocean floor is forced under the continental plate, and melts back into magma.
What forms features on the ocean?
What causes ocean floor features to form
How did the volcano form on ice in Iceland?
It didn't form on ice. Iceland is part of the mid Atlantic Ridge. The Mid Atlantic ridge is a mountain range along the floor of the Atlantic ocean. Iceland is part of this mountain range that protrudes above the ocean. This mountain range is the longest mountain range in the world. So in fact the ice formed on the volcano not the volcano on the ice.
