Sediments derived primarily from the products of weathering on the continents are called a. terrigenous sediment b. biogenous sediment c. hydrogenous sediment

Option A, Terrigenous sediment

Explanation:

Terrigenous sediments are formed by weathering of rocks on land especially the ones that are exposed to land. These rocks are transported by rivers, winds and even ice. The deposition of these sediments is limited to the continental shelf.  

While biogenous sediment are made up of non soluble remains of dead life forms on the planet and hydrogenous sediments are formed by exchange of ion /precipitation between the ocean water and sediments.  

Thus, it can be said that  terrigenous sediment are derived from products of weathering on the continents

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
