What Are Two Bad Things About Plate Tectonics? Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of the many tectonic plates that make up the Earth’s outer shell. The most powerful of these natural hazards occur in subduction zones, where two plates collide and one is thrust
What Are The Two Forces That Cause The Continents To Move? The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions What are 2 pieces of evidence for continental
What Characterizes The Transform Plate Boundaries? Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault What characterizes the convergent and transform plate boundaries?
What Can You Say About The Continental Drift Theory? Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener What is the importance of continental drift theory? continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during
What Do The Lithosphere And Asthenosphere Have In Common? Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth’s outermost layer, the crust, and the uppermost portion of the mantle. … The asthenosphere is more dense and viscous in comparison to the lithosphere. How
What Could Happen In The Future As The Tectonic Plates Continue To Move? Plate tectonics moves the continents around on a scale of 100s of millions of year. … On a more immediate time scale, earthquakes are a signal that the plates are still moving about and we can expect to see a continuation of
What Did Wegener Use To Support His Theory Of Continental Drift? Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. What supported the continental drift theory? Fossils of similar organisms across widely disparate
What Doctrine Of Earth Science Implies That Major Features On The Surface Of Earth Are Created By Sudden Short Lived Violent Events? Along with Charles Lyell Which of the following is a correct assumption about the age of the rock layers in the Grand Canyon? Which of the following is a correct assumption about the
What Do You Call The Supercontinent Landmass For Million Years Ago? Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. The land on Earth is constantly moving. Over millions of years, the continents broke apart from a single landmass called Pangea and moved to their present
What Evidence Supports The Theory Of Continental Drift? Alfred Wegener What are 4 pieces of evidence that support the theory of continental drift? The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations. What are the evidence
