the diagram below shows some ocean floor features.

which of these statements is correct about the feature labeled a in the diagram?

it is an underwater basin caused by subduction.

it is a deep trench located on both sides of a mid ocean ridge.

it is the part of the ocean floor where new crusts are formed.

it is the portion of the ocean floor where old crusts are eroded.

The correct answer is - It is the part of the ocean where new crusts are formed.

The place marked with A on the map is the place in the ocean where the new crust is formed. That is a place where there's a divergent plate boundary, or rather a place where the tectonic plates are moving away from one another. The gap and cracks left between them are easy target for the magma from the mantle to penetrate towards the surface. As the magma reaches the ocean floor it starts to cool off very quickly, creating new crust, and slowly making a very large underwater mountain range known as mid-ocean ridge.

yup its correct its: c) b b

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
