Who proposed the Continental Drift Theory in 1912?, Harry Hess, Robert S. Dietz, Alfred Wegener, Isaac Newton, The earth's rigid outer layer that is divided into tectonic plates is called the:, Asthenosphere, Mantle, Lithosphere, Core, what is the semi-fluid layer beneath The lithosphere over which tectonic plates move?, Crust, Core, Hydrosphere, Asthenosphere, The Seafloor Spreading Theory, which provided a mechanism for continental movement, was proposed by:, Alfred Wegener, Charles Darwin, Galileo Gallili, Harry Hess and Robert S. Dietz, Which type of plate boundary is formed when two tectonic plates collide?, Divergent, Convergent, Transform, Destructive, The movement of tectonic plates is primarily driven by which mechanism in the mantle?, Ocean waves, Wind Currents, Convection Currents, Gravitational Pull, Alfred Wegener was fully able to explain the exact mechanism behind the movement of continents when he proposed his initial theory., True, False, According to Seafloor Spreading Theory, new oceanic crust is formed at mid-ocean ridges due to volcanic activity., True, False, At divergent plate boundaries, tectonic plates move apart from one another., True, False, What is the process called when outer layers of rocks expand due to daytime heat and contract due to nighttime cold, causing them to peel away?, Frost-Action, Chemical Weathering, Exofoliation, Mass movement, Which geological feature is formed specifically due to chemical weathering, Granitic peeling, Cavities and sinkholes, Rock cracks from ice, Soil layers, what ancient deep sea once existed where the Great Himalayas stand today?, Tethys, Arabian Sea, Bay of Bengal, Siachen, What primary force drives mass movements by pulling loose rock masses and materials downwards?, Wind pressure, Hydraulic Action, Gravity, Crustal expansion, Which agent of denudation is specifically mentioned as being most significant in desert areas like the Thar and Sahara?, Sea waves, Glacier, Winds, Rainwater, The movement of glaciers is responsible for eroding V-shaped river valleys into which shape?, Flat plains, Deep gorges, Narrow canyons, U-shaped valleys, When water-saturated rock debris moves down the channels on steep hill sides, it is called a:, Earth flow, Mud flow or Landslide, Glacier, None of these, Into how many stages is a river course usually divided based on water supply and land slope?, Two, Three, Six, Seven, What is the first stage of a river course called?, The Upper Course or Mountain Stage, The Final Course or Ocean Stage, The Middle Course or Plain Stage, The Lower Course or Delta Stage, How does cutting trees indiscriminately directly lead to the automatic degradation of land?, It increases the water supply of nearby rivers., It creates U-shaped valleys., It causes immediate volcanic activity., It results in no rains, which degrades the land., Man has been accessing underground water since "time immemorial" primarily by doing what?, Building Factories, Digging Wells, Creating dams, Dumping Waste
