Answer:
they are the most common rocks exposed on the Earth's surface. They cover 75% area of the Earth
Explanation:
Answer:
Constructive margins occur when two plates with the same density (continental or oceanic) move away from each other, which causes magma from the mantle to rise to the surface. ... Destructive margins occur when one plate is denser than another and move towards each other.

<span>The features that might allow
you to identify Upwarped Mountains is that the altitude is greater than the
land. It has a high elevation and also high relief compared to other mountains
and it was formed through sediments that continuously stretch or tear.</span>
Answer:
Metamorphic rocks (from the Greek meta, change, and morphe, form, "change of shape") result from the transformation of pre-existing rocks that have undergone structural and mineralogical adjustments under certain physical or chemical conditions, or a combination of both, such as the temperature, pressure and / or chemical activity of the fluids agents of metamorphism These adjustments, imposed exclusively under the surface, transform the original rock without losing its solid state, generating a metamorphic rock. The rock generated depends on the composition and texture of the original rock, the agents of metamorphism, as well as the time in which the original rock was subjected to the effects of the so-called metamorphic process. Due to the nature of their origin, there may be a complete gradation between metamorphic rocks and the igneous or sedimentary rocks from which they were formed. The study of these rocks provides very valuable information about the geological events that occurred within the Earth and about their variation through time.
Explanation:
To classify a metamorphic rock, the type of metamorphism involved must be known, which can be variable since it depends on the criteria that are taken as a basis to differentiate it: it can be classified from the point of view of extension, fit and cause , geological value, increase or decrease in temperature, etc., but it is very common to define three main types of metamorphism according to the predominant metamorphic agent: Regional, Contact and Dynamic.
