What contribution did hess make to science?
He propounded the Sea-floor Spreading Theory.
What evidence caused Alfred Wegener to develop his hypothesis of continental drift?
One of His Theorys of continental drift was, that you could fit the continents back together if you had pictures. Also it would make up Pangea

What process makes new crust when the sea floor moves apart and magma rises up?
The process that makes new crust when the sea floor moves apart and magma rises up is called seafloor spreading. Magma from the mantle rises to the surface at mid-ocean ridges, cools, and solidifies to form new crust as the tectonic plates move apart. This process contributes to the continuous growth of the seafloor and the expansion of the ocean basins.
What is Archie Carr's contribution to continental drift?
Archie Carr's proposing theory that as Brazil spread away from the Mid-Atlantic ridge and Ascension Island, the green turtle returned to the island year after year to lay eggs. The hatchlings would have to swim back further each time 2cm/yr until today when they swim back 1200 miles. I believe this to support Wegener's theory.
Who was the scientist who contributed to the plate tectonics theory?
A man named Alfred Wegener first put out the theory of continental drift. That theory then evolved into sea floor spreading when a man named Harry Hess discovered that there are underwater mountain ranges spreading laterally away from them. That then arrives at the current theory of plate tectonics.
Alfred wegener's hobbies?
he loved to sew and make bracelets with his 12 daughters
What is Alfred wegener famous for?
Alfred Wegener is famous for discovering plate tectonics. Basically, he discovered that plates make up the Earth like jigsaw pieces and these are continents.
What are facts about Alfred wegener?
Alfred Wegener was a German meteorologist who proposed the theory of continental drift in 1912. His theory suggested that continents were once joined together in a single landmass called Pangaea and later drifted apart to their current positions. Despite facing skepticism initially, Wegener's hypothesis laid the foundation for the modern theory of plate tectonics.
What is the role of mid ocean ridge in sea floor spreading?
to make volcanoes
What contribution did hess make to science?
He propounded the Sea-floor Spreading Theory.
What do you think is causing the ocean floor to increase in size?
Sea Floor Spreading and the way the volcanoes erupt make the mountains erode into the ocean.
What contributions did Alfred Wegener make toward science?
Alfred Wegener was a German meteorologist and geophysicist who proposed the theory of continental drift in the early 20th century. His theory suggested that the Earth's continents were once connected and have since drifted apart over millions of years. Though initially met with skepticism, his work laid the foundation for the development of the modern theory of plate tectonics.
What discovery did scientist make when comparing the age of the sea floor to that of the continents?
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
What evidence caused Alfred Wegener to develop his hypothesis of continental drift?
One of His Theorys of continental drift was, that you could fit the continents back together if you had pictures. Also it would make up Pangea
Are the rocks that make up the ocean floor older or younger than those that make up the continents?
same age. the ice caps just melted on top over the rocks at the bottom of the sea.
About sea floor spreading?
Sea-floor spreading is what happens when the plates in the earth's crust move apart. During this movement of the plates, magma wells up from deep within the earth and fills in the cracks, forming a new oceanic crust, or sea-floor.
