What is a oceanic ridges?
a ridge in the ocean
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.
Earth's radius and surface area are slowly increasing to accommodate the new oceanic crust being formed at mid-oceanic ridges - true or false?
False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.
What is oceanic ridges?
a ridge in the ocean
Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
Is the size of the earth increasing due to oceanic crust being produced?
No, the size of the Earth is not increasing due to oceanic crust being produced. The creation of oceanic crust at mid-ocean ridges is balanced by its destruction at subduction zones, resulting in a process known as plate tectonics where the Earth's surface remains relatively constant in size.
Earth's radius and surface area are slowly increasing to accommodate the new oceanic crust being formed at mid-ocean ridges. True or False?
False. The Earth's radius and surface area are not increasing to accommodate new oceanic crust. Instead, the process of seafloor spreading at mid-ocean ridges involves the creation of new oceanic crust, which is balanced by the destruction of crust at subduction zones, maintaining the Earth's overall surface area.
What is mid - oceanic ridges?
mountainous topography
Where is oceanic crust created?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
What is the relationship between distance from the ridges and age of the crust?
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.
Is it true that Earth's radius and surface area are slowly increasing to accommodate the new oceanic crust being formed at mid-ocean ridges?
No, Earth's radius and surface area are not increasing to accommodate new oceanic crust. The process of seafloor spreading at mid-ocean ridges is balanced by subduction, where older crust is recycled back into the mantle. This maintains the overall size of Earth and its surface area.
Is it true that The Atlantic and Pacific basins have oceanic ridges and the Indian Ocean has no oceanic ridge?
