How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
What are the 4 layers of the rainforest?
the layers (going down) are the emergent layer, then the canopy layer, the understory layer the the forest floor. The emergent layer - the emergents are the tallest trees so they can get sunlight. The canopy layer - the canopy is the thickest layer of the rainforest. Understory/Undercanopy - This layer has young trees, short trees and bushes. Forest floor/Shrub layer - There are few plants in this layer that have adapted to low-light.

Matthew Henson went to the college of mack Moro if you belive this you are stupid just kidding
Why are sedimentary rocks on the bottom of the oceans younger than similar rocks found on the continents?
== == Sedimentary rocks on the bottom of the oceans are younger because the ocean floor is constantly recycling itself. Oceanic plates are being added to at the oceanic ridge, and being destroyed by subduction when colliding with continental plates. Sedimentary rocks on continents are definitely subject to erosional forces, but not generally to plate destruction forces.
Females have muscular organs in which the young develop?
Young are developed in the uterus (womb).
Where do you find young seafloor?
in the depths of the oceanic crust floor.
How did research from the Glomar Challenger help scientist support the theory of seafloor spreading?
Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.

Do these plates move?
Dr. Alfred Wegener proposed the continental drift theory which states that the lithosphere drifts apart because of the gravitational pull of the moon. Harold Jeffreys contradicted the idea. He said that if Dr. Wegener's proposal is true, then the gravitational pull of the moon could stop the Earth from moving. The Earth is still moving today. There is another theory called Seafloor Spreading which states that the oceanic crust moves apart forming cracks. The magma goes through these cracks and up until it cools. When it cools it sinks and goes through the cracks. This is why our seafloor is very young. The sea floor is recycled. The most acceptable theory is the Plate Tectonics theory which is the combination of Continental Drift Theory and Sea floor Spreading. I hope this helped you a lot. This is a stranger helping a stranger. I hope this will strengthen our mutual relationship. Thank you!
What is the young ocean floor?
The Young Ocean Floor is the part of the mantle showing between the 2 split tectonic plates.
How and why guyots shaped the way they are?
A guyot is a flat topped underwater volcano or seamount. These represent ancient volcanoes that were probably surface features when young. Perhaps even coral atoll's. With sea-floor spreading, these are moved into progressively deeper water.

What is a sentence using the word young?
It was a young crowd that assembled for the concert. It was the young man that brought to motion to the floor.
Why are sea floor rocks so young?
Rocks on the sea floor are very young because most have resulted from recent volcanic activity. Volcanic activity is constantly erupting on the ocean's floor and creating new rocks.
What is a mountainous chain of young basaltic rock at the active spreading center of an ocean?
an oceanic ridge
