The answer is letter C.
Terrigenous sediments come from continental rocks, meaning they come from inland. The erosion of rocks from the environment (e.g. volcanic eruptions, rock weathering) causes the development of these sediments. These sediments may consist of sand, mud, and silt, that are usually carried to bigger bodies of water by rivers.<span />
Answer: Food is the basic need for all life forms on earth. The food requirements for humans is the basic requirement to sustain their life and function.
Explanation:
Some countries face the scarcity of the food due to feminine, scarcity of food, drought, pandemic, lack of proper agricultural practices, increase in demand and low productivity, and for other reasons. Such problems are of global concern. The resolution of such problems include promotion of agricultural practices, availing food to the poor at low or no cost, adoption of meat culture in the form of fish, poultry and beef to support the food demand of the large human population, finding more varieties of plants in the wild that can be edible, easily grown and cultivated, asking people not to waste food in marriages, seminars, and other functions instead supplying the left over food to old age homes, shelter homes, orphanage, and regions which are affected by scarcity of food is a better option.
Peridotite is the pieces of green olivine-rich mantle rock that are sometimes carried to the surface by basaltic lava.
The silicate minerals olivine and pyroxene make up the majority of the composition of peridotite, which is a dense, coarse-grained igneous rock.
Because the rock has less than 45% silica, peridotite is ultramafic. Because it contains significant amounts of the magnesium-rich mineral olivine, it has a high magnesium content (Mg2+). Peridotite originates in the Earth's mantle, either as crystals gathered from magmas that erupted in the mantle or as solid blocks and pieces.
Peridotites from these layered igneous complexes have a variety of compositions that reflect the relative amounts of pyroxenes, chromite, plagioclase, and amphibole.
The term "peridotite" derives from the mineral peridot, which is made up of light green olivine.
