Answer:
mechanical weathering
Explanation:
As a definition, mechanical weathering is the disintegration and decomposition of rocks on or on the earth's surface produced by different atmospheric, climatic and biological agents.
Weathering is a permanent process in nature.
It is also defined as a static process by which the rock breaks into small fragments, dissolving and decomposing to form new minerals. This is the way in which the removal and transport of detritus then results in erosion. It follows that weathering, by reducing the consistency of the stone masses leads to the erosion process.
The causative agents of the weathering of the stones, (external geological agents) can be physical (mechanical), chemical and biological.
Answer: volcanic activity
Explanation: The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born. The material that erupts at spreading centers along the mid-ocean ridge is primarily basalt, the most common rock on Earth.
