How Does Continental Drift Explain Plate Movements? Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. … Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate
How Does Convection Cause The Motion Of Plates That Drives Plate Tectonics? Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. … Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of
How Does Convection Affect The Inside Of The Earth? Convection currents play a role in the circulation of fluids. Convection currents are the result of differential heating. … 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.
Are Fish Different Wallace Line? Although many zoogeographers no longer consider the Wallace Line to be a regional boundary, it does represent an abrupt limit of distribution for many major animal groups. Many fish, bird, and mammal groups are abundantly represented on one side of the Wallace Line but poorly or not at all on
What Are The Four Evidence Of Continental Drift Theory? 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 four pieces of evidence for continental drift quizlet? List four pieces of evidence for Wegener’s
Is When The Cooler Denser Material Sinks And The Warm Material Rises To The Surface? As the water at the bottom of the pot is heated, the water at the bottom expands and becomes less dense than the cooler water above it. The cooler, denser water sinks, and the warmer water rises to the surface
How Do The Shapes Of South America And Africa Support The Theory Of Plate Tectonics? However, many other types of evidence also support the theory of plate tectonics. … South America and Africa were once together, but were split apart by the formation of a diverging plate boundary. This is confirmed by matches between the
What Happens When 2 Continental Tectonic Plates Collide? If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. … The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along
What Evidence Did Wegener Make Use Of To Develop The Theory Of Continental Drift? Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to
How Did Alfred Wegener Define Pangaea And How He Explained The Continental Drift? Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his
