How did vien minerals deposits get in empty spaces?
Deep in the Earth, minerals are dissolved in the hot, high pressure water underground. That water seeps upwards into cracks in the rock. As it rises, it both cools and lowers in pressure. These reduce the ability of the water to hold the minerals in solution. The minerals crystallize in the cracks, forming the veins of mineral ore.
What prevents blood from flowing in veins?
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
How can mineral veins form?
Typically, geological mineral veins were created by glacial movement. As the glaciers cut through the surface of the land, they deposited the minerals that are found beneath the surface today. Answer by FutureLPGAgolfer Cooling Lava, cooling magma, and evaporation.
