Where do new sections of crust come from during seafloor spreading?

Geography
1 answer:
VashaNatasha [74]3 years ago
5 0

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.

Fill in the blank:
bagirrra123 [75]

Answer:

Mid oceanic ridges.

Explanation:

  • As divergence is defined as constructive plate boundary with opening in between the two slabs of tectonic rock being an heavy and oceanic plate the divergence is found mostly in where the new lava flows are being created and the newer rock are thus located near to the surface of the ridges as a result of the upwelling of hot molten lava from the magma chambers below.
  • Other examples being the mid-Atlantic ridge, red sea ridge, and eastern pacific rise.
  • And other popular ridges in the world that have lava flowing from the base and thus demarcate the divergent boundaries with continental crustal movement based on some sentiments form below, as slab push and slab pull.

As deltas are depositional features of fluvial processes, so blank are depositional features of eolian (wind) processes.
lina2011 [118]

The correct answer is - dunes.

The dunes, or sand dunes, are a relief forms that are formed by deposition of material. In the process of forming a dune, the responsibility goes to the eolian processes (wind processes). The wind has its own mechanical power to erode the rocks, but it also has the power to transport the material. The stronger the wind, the bigger the particles it can transport, and vice versa. When the wind is transporting a certain material, in the case of the dunes it will be sand particles, eventually it will start to lose on speed, and as it loses on speed, it loses on power, so the sand particles are starting to fall on the ground and deposit. s more and more sand particles are depositing, the dune starts to form, and it is growing bigger as more sand particles are falling on it.
