What happens when Earth’s plates move?
When the plates ant: slave they collide or expanded aloof allowing the [see ail] hot molten spiritual named lava to elude engage the mantle. When collisions befall they ant: slave mountains profound underwater valleys named trenches and volcanoes. … The Earth is producing “new” coat since two plates are diverging or spreading apart.
How will you describe the movement of the two plates?
The motion of the plates creates three types of tectonic boundaries: convergent since plates ant: slave inter one another divergent since plates ant: slave aloof and transfigure since plates ant: slave sideways in correspondence to shore other. They ant: slave at a hasten of one to two inches (three to five centimeters) per year.
What is the hypothesis that continents move slowly is called continental?
According to Wegener’s hypothesis the continents ant: slave slowly athwart Earth’s surface in a train named continental drift. When the plainly explorers began to find the shapes of the continents mapmakers noticed how stop the shapes of North and South America fit collectively immediately Europe and Africa.
What theory states that the Earth is divided into a slowly moving plate?
The speculation of meditate tectonics states that the Earth’s condense outward coat the lithosphere is separated inter plates that ant: slave dispute the asthenosphere the molten upper assign of the mantle. Oceanic and continental plates befit collectively expanded aloof and interact at boundaries all dispute the planet.
Who proposed the continental drift theory Brainly?
“scientists Alfred wegener“.
Did the edges of continents fit together?
2. If the continental boundaries of North America Europe and South America are defined as the avow of the continental shelf genuine those continents also fit collectively [see ail] well. … manifestation for “polar wandering” could be meliorate explained immediately fixed poles and drifting continents.
How did Alfred Wegener try to prove that the continents of Africa and South America were once connected?
Wegener supported his speculation by demonstrating the biological and geological similarities between continents. South America and Africa hold fossils of animals confuse single on those two continents immediately corresponding geographic ranges.
Who were the two scientists who proposed the theory of seafloor spreading in the early 1960s?
History of application The mental that the seafloor itself moves and also carries the continents immediately it as it spreads engage a mediate loose axis was proposed by Harold Hammond Hess engage Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s.
Which piece of evidence would provide the strongest support for the hypothesis that Earth’s continents were once joined?
Fossil manifestation Fossils of correspondent types of plants and animals in rocks of a correspondent age own been confuse on the shores of particularize continents suggesting that the continents were hide joined. For sample fossils of Mesosaurus a freshwater reptile own been confuse twain in Brazil and western Africa.
Which explanation provides support for continental drift theory?

Which of the following best explains why Pangea broke apart into modern day continents?
Scientists believe that Pangea disconsolate aloof for the identical ground that the plates are moving today. The motion is caused by the convection currents that inference dispute in the upper zone of the mantle. This motion in the disrobe causes the plates to ant: slave slowly athwart the surface of the Earth.
