Summarize the evidence that supports wegner's hypothesis?
The evidence that supports Wegner's hypothesis is that in 1947 , a group of scientisits noticed two things about the Mid- Atlantic Ridge. The first thing that the scientists noticed was the sediment that covers the sea floor is thinner and younger closer to a ridge than it is farther from a ridge. Second, scientists learned that the ocean floor is very young. Radiometric dating shows that the sea floor closer to the mid-ocean ridge are younger, than the ones farther.
Why do scientists look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.
The smell of an ammonia solution used to clean a floor can quickly be detected throughout a house Scientists explain this phenomenon by theorizing that gas molecules from the ammonia are in continuo?
Scientists have observed tiny smoke particles moved by unseen particles in a rapid, irregular fashion
What is the difference of a gully trap drain from a floor drain?
The difference between a gully trap drain and a floor drain is placement. A floor drain is in a floor, a gully trap drain goes on an external wall.
How do scientists make maps of the ocean floor?
Sonar
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
What are the scientist who work on the ocean floor called?
Scientists who work on the ocean floor are called marine biologist
What is the standard placement of a floor register from the wall?
You should only leave 1 inch between the wall and the start of the floor register. It is also recommended that the floor register be placed underneath a window.

What did scientists learn about the sea floor?
geology,oceans,seas
Why do scientists use sonar?
to calculate the depth of the ocean floor
How did scientists determine how the ocean floor is?
Radiometric Dating.. APEX!
