Mid-Ocean Ridge Activity

This activity is composed of naming the continents, identifying mid-ocean ridges, and also determining the age of the ocean floor. Once you have labeled each map appropriately, you should have the ability to answer the series of concerns that follow the exercise.

You are watching: Where is the youngest ocean floor found

The last map will allow you to explore all of the maps. Navigate by clicking through the images, which will carry out various views of the maps, and display the partnership in between the continents, mid-ocean ridges and the age of the sea floor.

Questions

Wbelow is the youngest sea floor located?
<HideAnswer>"> <Check Answer>
The youngest ocean floor is situated on the mid-sea ridge.
Wright here is the oldest ocean floor located?
<HideAnswer>"> <Check Answer>
The earliest ocean floor is located near the continents, beside a subduction zone.
There are rocks on eexceptionally continent that are 3 to 4 billion years old. Why are tbelow no oceanic rocks older than 200 million years?
<HideAnswer>"> <Check Answer>
Oceanic crust is inevitably destroyed in subduction zones. Although oceanic crust has been creating on Earth for over 4 billion years, all of the sea floor older than around 200 million years has been recycled by plate tectonics. Continental crust is not subducted and ruined, so incredibly old continental rocks have actually endured.
In the eastern Pacific, why are oceanic rocks no older than 120 million years?
<HideAnswer>"> <Check Answer>
The eastern Pacific Mid-Oceanic Ridge is not much from the subduction zone that runs alengthy the west shore of South America. The ocean floor spanalysis eastward is subducted and ruined relatively soon after formation.
Based on the circulation of color on the map, which ridge is spanalysis quicker, the Mid-Atlantic Ridge or the East Pacific Rise (ridge and also rise are both nicknames for a mid-oceanic ridge)?
<HideAnswer>"> <Check Answer>
The East Pacific Rise is spanalysis faster than the Mid-Atlantic Ridge. The wide swath of red and also orange parallel to the East Pacific Rise illustprices that a huge area of oceanic rocks are incredibly young.
Based on the distribution of color on the map, which ridge is spreading much faster, the Mid-Atlantic Ridge or the Southeastern Indian Ridge?
<HideAnswer>"> <Check Answer>
The Southeastern Indian Ridge is spanalysis much faster than the Mid-Atlantic Ridge.

How does the rate of spanalysis of the Southeastern Indian Ridge compare to the Southwest Indian Ridge?
<HideAnswer>"> <Check Answer>
The Southeast Indian Ridge is spanalysis quicker than the Southwest Indian Ridge.

Critical Thinking

If the mid-sea ridges energetic today continue to create new sea floor for an additional 100-200 million years, how will certainly the appearance and location of oceans and continents be changed?
<HideAnswer>"> <Possible Answer>
Scientists seek to understand also and describe how the herbal world functions. Many type of of the questions raised in this undertaking have no absolute answers.The Pacific Ocean will most likely disshow up, swallowed up by subduction on its margins. The Atlantic will have actually widened enormously, pushing North and South America into Asia, Indonesia, and Australia. This brand-new, large land also mass will certainly most likely be shoved much to the north by the spanalysis along the ridges that circle Antarctica, leaving that icy continent virtually alone in the southern hemisphere.
