Which Of The Following Best Explains Why Earth Is Tectonically Active? Which of the following best explains why Earth is tectonically active? A Earth’s solid surface layer rotates more rapidly than the layers beneath it. Why is the earth tectonically active? Tectonic activity is caused by heat loss; all the terrestrial planets passed through a
What Most Likely Caused The Tilting Of The Grand Canyon? Scientists observe several strata that are tilted at an angle. What most likely cause the tilting? Scientists believe that the boundary stratum between the Cretaceous and Paleocene periods were caused by an asteroid. What caused the tilting in the Grand Canyon? The Uplift of the
Why Is The Asthenosphere Important To Plate Tectonics? Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. … According to the theory of plate tectonics, the asthenosphere is the repository for older and denser parts of the lithosphere that are dragged downward in subduction zones.
Which Processes Are Caused By Convection Currents In The Mantle? Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents. Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions. What
What Was The Major Flaw In The Hypothesis Of Continental Drift? The main problem with Wegener’s hypothesis of Continental Drift was the lack of a mechanism. He did not have an explanation for how the continents moved. His attempt to explain it using tides only made things worse. But both Galileo and Darwin had serious
What Type Of Stress Causes The Formation Mountains? The force of compression can push rocks together or cause the edges of each plate colliding to rise. Mountains are a result of high-impact compression stress caused when two plates collided. What type of stress causes the formation of mountains and mountain ranges? Subduction of oceanic lithosphere
Why Is The Asthenosphere So Important To Plate Tectonics? Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. … According to the theory of plate tectonics, the asthenosphere is the repository for older and denser parts of the lithosphere that are dragged downward in subduction
What Was The Early Theory Of Continental Drift? The theory of continental drift is most associated with the scientist Alfred Wegener What was the early evidence for continental drift? In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for
Where Are Tectonic Plates Most Active? Most of the world’s active volcanoes occur along plate boundaries – the Pacific plate’s Ring of Fire is the most active. New Zealand is right on the edges of two tectonic plates – the Australian and Pacific – and we get plenty of the action that goes with it!
What Evidence Supports Wegener’s Continental Drift Hypothesis Quizlet? What evidence supported Wegener’s hypothesis? Wegener gathered evidence from different scientific fields to support his ideas about continental drift. He studied land features, fossils, and evidence of climate change. You just studied 30 terms! Which evidence does support Wegener’s concept of continental drift? Evidence for continental drift
