Answer:
Environment plays an important role in living and the existence of life on earth. Earth is a home for many living species and we all are dependent on the environment for food, air, water, etc.
Explanation:
Just like convection in air, when denser water sinks, its space is filled by less dense water moving in. This creates convection currents that move enormous amounts of water in the depths of the ocean.
The sediments that is composed of mineral grains that are
eroded from the continental rocks is called terrigenous. The terrigenous
sediments are obtained from the erosion of rocks that occurs on land and that
they are being stored in the submarine canyons.
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.
