What Are The 4 Evidences Of Seafloor Spreading?

What Are The 4 Evidences Of Seafloor Spreading? Harry Hess’s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. This evidence was from the investigations of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes. What are 3 types of evidence for seafloor spreading?

What Causes The Ocean Floor To Spread?

What Causes The Ocean Floor To Spread? Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. What are two pieces

What Caused The Continental Shelf?

What Caused The Continental Shelf? Over many millions of years, organic and inorganic materials formed continental shelves. Inorganic material built up as rivers carried sediment—bits of rock, soil, and gravel—to the edges of the continents and into the ocean. What is continental shelf theory? The term “continental shelf” is used by geologists generally to mean

What Is It Called When The Ocean Floor Sinks Back Into The Mantle?

What Is It Called When The Ocean Floor Sinks Back Into The Mantle? Subduction is the process by which the ocean floor sinks beneath a deep-ocean trench What happens to the old seafloor as it is pushed into the mantle? When the seafloor subducts it does disappear from the surface. It moves deeper into the

What Is The Correct Order Of Seafloor Features From The Coast To The Mid-ocean Ridge?

What Is The Correct Order Of Seafloor Features From The Coast To The Mid-ocean Ridge? The correct order of seafloor features from the coast to the mid-ocean ridge is: shelf, slope, rise, abyssal plain. Is the seafloor the oldest at the mid ocean ridges? The oldest seafloor is comparatively very young, approximately 280 million years
