What two scientist proposed the theory of seafloor spreading in the early 1960s?
Alfred wegner
Would a metal bridge be longer or shorter in the summer Why?
It would be longer. Metal is a good conductor of heat, Heat makes a material expand because the particles within it have more kinetic energy, therefore they vibrate more, which makes them slightly further away from each other which increases the space a material takes up.
If divergent plates cause new land to be added to the Earth why doesn't the Earth just grow and grow?
While divergent plates do create new land through processes like seafloor spreading, the Earth doesn't continually grow because this new land is balanced by subduction, where tectonic plates are pushed back into the mantle at convergent boundaries. The Earth's size remains relatively constant as the material created at divergent boundaries is offset by the material lost at subduction zones. Additionally, the recycling of crustal material ensures that land is constantly being transformed rather than simply accumulating.
Can you download ps2 bios free?
The only LEGAL way of obtaining a bios is dumping it from your OWN Playstation 2 console That's because the ps2 BIOS is a copyrighted material of Sony and that makes its' distribution illegal.
What is the coldest material on earth?
- for a natural material: a stone from Antarctic- for a manmade material: solid helium
How is seafloor spreading different continental drift?
seafloor spreading is when molten material rises and cools down and makes new seafloor, continental drift is the theory that the continents were once together and the big land mass is called Pangea.this is fake story no one believe it i got wrong
Magnetic stripes on the seafloor are caused in part by?
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor. This phenomenon provides evidence for seafloor spreading and plate tectonics.
How is continental drift different from seafloor spreading?
seafloor spreading is when molten material rises and cools down and makes new seafloor, continental drift is the theory that the continents were once together and the big land mass is called Pangea.this is fake story no one believe it i got wrong
How does the thickness of a given slab of seafloor affect its weight?
The thicker the slab of seafloor, the more material it contains, leading to a greater weight. This weight is influenced by the density of the rock forming the seafloor. Thicker slabs of seafloor would have more mass and therefore weigh more than thinner slabs.
How do you explain the process of the seafloor spreading?
The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor
Does magma produce new material when it rises from an ocean ridge?
Yes, when magma rises from an ocean ridge, it can produce new material through a process called seafloor spreading. As the magma reaches the surface, it cools and solidifies, forming new oceanic crust. This process contributes to the continuous expansion of the seafloor and the formation of new crustal material.
What makes up the seafloor?
Dead critters and plants, soil and minerals that cannot stay in solution.
Which material makes up Mount Rushmore?
The material that makes up Mount Rushmore is granite.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
What is a material tailoring?
a material tailoring is a person who makes clothing
