They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
Sonar
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.
Sea Floor Spreading
Scientists who work on the ocean floor are called marine biologist
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.
Radiometric Dating.. APEX!
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
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.

Scientists use sonar to map the ocean floor by sending sound waves from a ship to the ocean floor. These sound waves bounce back and are picked up by a receiver on the ship, providing information about the depth and texture of the ocean floor. By analyzing the time it takes for the sound waves to return, scientists can create detailed maps of the underwater terrain.
