The melting temperature of materials is affected by the pressure they are under. So when "rock" in the Earth's mantle experiences a decrease in confining pressure, not only does it expand, it's melting temperature drops. If the melting temperature of the material drops below the background (also known as the
in-situ
) temperature, then melting will occur and in this case magma will form.
Answer:
The physical topography of a mountainous region is the most influenced by the movement of tectonic plates.
Explanation:
The first option is not correct because the precipitation at a certain place is influenced by numerous factors, not just by the landforms created by the movement of the tectonic plates.
The second option is not correct because the seasonal changes in the weather are mostly due to the latitude at which a place is located.
The third option is not correct because the distribution of biomes depends on numerous factors, not just one.
The fourth option is correct because the physical topography of a mountainous region is directly connected with the movement of the tectonic plates, as that is the process that creates these regions.
