Answer:

Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.

Explanation:

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. Eventually, the crust cracks.

What is the acceleration of a marble in that has a mass of 90kg and a force applied of 60N
miskamm [114]

Answer:

0.6... or 3/5

Explanation:

To find the acceleration, we need to use the acceleration formula:

  • a=F/m

So all we have to do now is plug in the numbers:

  • a = 60/90

Once we divide 60 by 90, we will get the acceleration of the marble.

  • 60/90 = 0.6... (repeating)

Our final answer should be:

0.6... or 3/5
