If you add the two lengths on the left, you can figure out that one side is 100 units and the base is 50. In the smaller triangle, the ratio of base length to side length should be the same. If the big triangle is 50:100, then the small triangles base should be 1/2 it’s side. 1/2 of 60 is...
30 units
Hope this helps :)
Answer:
Porosity
Explanation:
Porosity is defined as the total percentage of pore spaces that are present within a rock. These spaces are found between the rock particles and fractures and are mostly filled with fluid mixture or water. It is the ratio between the total pore space in a rock to the total volume of the rock. It is mainly calculated in terms of percentage.
Porosity is directly affected by sorting. Well-sorted rocks indicate high porosity but poorly-sorted rocks indicate low porosity. Some of the examples of rocks exhibiting high porosity are limestone, shale, and sandstone. Rocks with low porosity include granite and mudstone.
Ocean currents act much like a conveyor belts, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
I know for sure the ganga and brahmaputra rivers do make up the northern plains, not sure about the yamuna. but since two do, then i would answer all of these
