Convergent-compressive
Divergent-tensional
Transform-shear
The correct answer is - B) convection currents in the mantle.
There's multiple tectonic plates on the surface on the planet, around 17 from what is known so far, but as the scientific methods are developing there might be few more discovered in the years to come.
These plates are all moving, only few cm per year, but on the long term it influences and changes everything on the surface on the Earth.
The movement of the plates is the result of the convection currents in the mantle layer beneath. These convection currents are essentially the combination of the high temperatures, high pressures, and viscous metals, and they managed to break up the crust on the surface, and with its push force, they are slowly moving the plates.
With the movement of the plates and their collisions and moving away, lots of earthquakes and volcanoes are appearing all over the plate boundaries.
The evidence is when there is degradation. it is characteristic of channel networks in which either bedrock<span> erosion is taking place, or in systems that are </span>sediment<span>-starved and are therefore entraining more material than is being deposited. When a stream degrades, it leaves behind a </span>fluvial terrace<span>. This can be further classified as a </span>strath terrace<span>—a bedrock terrace that may have a thin mantle of </span>alluvium<span>—if the river is incising through bedrock.</span>
Answer:
Read the paragraph about social media.
Social media outlets are often criticized as forums for unimportant postings and uniformed rants. Though much of what is posted is conversational drivel, social media outlets also serve as springboards for entrepreneurs.
