<span>The best answer is (d) water from snowmelts. The American Southwest has many mountains that catch moist air moving westward (from the Pacific) that falls as snow during the winter. The snow melts gradually during the spring and summer when there is little precipitation. The melted snow runs off the mountains into rivers and streams that can be tapped by irrigation pumps. The snowmelt also sinks into the ground, replenishing underground aquifers that can be tapped by wells in the valleys where farming takes place.</span>

earnstyle [38]

Answer:

Q. 41. Basaltic Lava,   Q.43. Basaltic magma  Q.44. False

Explanation:

Basalt is a mafic extrusive igneous rock, formed by the rapid cooling of Mg and Fe rich lava, exposed at or near the surface of the earth. Thus forming about 90% of the surface lava on earth.

Shield Volcanoes emit lava or magma in the form of viscous basaltic lava. Highly explosive.

Greenland and Antarctica together constitute the 99% of the earth ice caps so, Greenland has about 80% cover as compared to antarctic 98% and both are depleting fast.
