How fast do America and Africa move apart?
America and Africa are moving apart at a rate of about 2.5 centimeters per year. This movement is due to the process of plate tectonics, where the North American Plate and the African Plate are moving away from each other along a divergent boundary, causing the Atlantic Ocean to widen over geologic time scales.
What was formed when these two continents split again 65 million years ago?
The continent of South America was formed when North and South America split from each other over 65 million years ago. North America is located in the Northern hemisphere and South America is located in the Southern hemisphere.
A divergent boundary at two continental plates can result in a?
rift valley formation. As the plates move apart, magma rises from the mantle, leading to volcanism and the creation of new crust. Over time, this process can widen the gap between the two plates, forming a rift valley.
What two plates are moving away from each other?
1. Pacific Plate and North American Plate 2. China Plate and Pacific Plate 3. Australian Plate and Pacific Plate 4. South American Plate and Nazca Plate 5. Eurasian Plate and African Plate 6. Eurasian Plate and Arabian Plate 7. Eurasian Plate and Australian PLATE 8. Scotia Plate and Antarctic Plate
How is an ocean submarine canyon formed?
An ocean submarine canyon is typically formed through a combination of processes such as erosion by currents, turbidity flows, and underwater landslides. These can carve deep, V-shaped valleys in the seafloor, similar to canyons on land. Over time, the canyon can deepen and widen as sediment is transported and deposited within it.
How much does the Atlantic ocean widen per year due to divergent boundary?
About 3 centimeters.
What caused the Atlantic ocean to widen?
seafloor spreading
The movement of plates is causing the Atlantic Ocean to shrink?
Plate tectonics is actually causing the Atlantic Ocean to widen, as the plates are moving apart in a process known as seafloor spreading. This creates new oceanic crust and widens the Atlantic Ocean basin over time.
How much does the Atlantic ocean widen per year?
The Atlantic Ocean widens at a rate of about 1 inch (2.5 cm) per year due to seafloor spreading along the Mid-Atlantic Ridge. This process involves the movement of tectonic plates, creating new oceanic crust and causing the ocean to gradually widen over time.
Which is the youngest ocean?
The Youngest Ocean is the Artic Ocean Because People thought the artic ocean froze over and was just ice.
What causes the Atlantic ocean to widen one to three inche per year?
the techtonic plates are shifting (the continents are moving away from each other)
What is happening because of that the Atlantic Ocean is growing?
The Atlantic Ocean is growing primarily due to the process of seafloor spreading at the Mid-Atlantic Ridge, where tectonic plates are pulling apart. As magma rises to the surface, it creates new oceanic crust, causing the ocean basin to widen. This geological activity also contributes to the movement of continental plates, leading to changes in coastlines and the distribution of landmasses over geological time. Consequently, the ongoing expansion of the Atlantic Ocean affects global ocean currents, climate patterns, and marine ecosystems.
How fast do America and Africa move apart?
America and Africa are moving apart at a rate of about 2.5 centimeters per year. This movement is due to the process of plate tectonics, where the North American Plate and the African Plate are moving away from each other along a divergent boundary, causing the Atlantic Ocean to widen over geologic time scales.
Is the Atlantic Ocean getting bigger or smaller?
The Atlantic Ocean is gradually getting bigger because of the sea-floor spreading that is happening. Sea-floor spreading is the process in which new oceanic lithosphere is made. And this mostly happens at Mid-Atlantic ridges. This is the process in which magma from under the Earth seeps to the surface and gradually solidifies. F.Y.I. they sift apart making magma rise from the earths manntle. The magma then turns into more crust that has been happining for mllions of years.
What will happen to the pacific ocean if the Atlantic ocean keeps getting wider?
The Atlantic will go on getting wider and wider, and will create a super ocean, but this will take many millions of years to happen.Lets look at some of the figures.The Mid Atlantic Ridge is widening the Atlantic Ocean by 0.4 to 4 inches (1 to 10 cms) a year. The average is about 1 inch (2.5 cm) a year.Taking the fastest speed, 4 inches (10 cm), it will take over 15,000 years to widen one mile.Multiply that by the width of the Pacific Ocean, 11,000 miles (17,700 km) at its widest point, and you are looking at 165,000,000 years for the Pacific Ocean to disappear.Don't forget that I used the fastest speed of widening, if you use the average speed, you will have to multiply 165 million by 4.
What has created the mid atlantic ridge running through iceland?
It is the volcanic eruptions which has widen over time.
The rate of plate movement along the Mid Atlantic Ridge has been determined to be 3 centimeters per year At this rate how long will it take the Atlantic Ocean to widen another one kilometer?
3 centimeters equal 1.18110 inches. To convert inches into kilometers you multiply that by 28560. So, 1.18110 times 28560 equals 33,732.216 years
