Forests do provide a habitat for many animals, so it's not c
SO the answer must be D. For reference, soil salinization is the process in which salt content increases in the soil.
Answer:
1. 
2. The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).
3.
m = 43.5 g
V = 50 mL
d = 43.5 g / 50 mL = 0.87 g/mL
Density of this cooking oil is 0.87 g/mL.
Explanation:
The Mariana Trench is the deepest part in the world's oceans. It is located in the Pacific Ocean and has a depth of -36,069'. It form the boundary between two tectonic plates, the Pacific Plate, and the Mariana Plate. The western edge of the Pacific Plate is subducted under the Mariana plate. The movement of these two plates is indirectly responsible for the formation of the Mariana islands, volcanic islands caused by flux melting.
