What evidence suggests that continents move?

The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

What causes continents to move prove it with evidence?

The causes of continental drift are perfectly explained by the plate tectonic theory. The earth’s outer shell is composed of plates that move a little bit every year. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.

What are the 5 evidences of continental drift?

They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

What were the 4 main evidence 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.

Which of the following provides evidence of plate motion?

Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species.

Which of the following provides evidence that the continents were once connected?

Matching rock type and rock formations can show the way the continents were once attached. Glacial evidence has been found in areas where glaciers could exist if the continents were in their current location. … Fossils of the same plants and animals are found on widely separated continents.

Which of the following provides evidence that the Earth’s continents were once in different positions than they are today?

Which of the following is the best evidence that Earth’s continents were once in vastly different positions than they are today? Fossils of tropical plants are found in Antarctica. You just studied 33 terms!

What causes the plates to move?

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other.

What causes the plates to move quizlet?

convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.

What causes tectonic plates to move and what evidence do we have that they have done so?

What causes tectonic plates to move, and what evidence do we have that they have done so? Plate tectonics move by mantle convection currents. Rock formations and fossils are evidence.

What causes tectonic plates to move and what evidence do we have that they have done so quizlet?

The plates move due to convection currents in the mantle. The evidence of this movement is shown in three continents having similar rock formations (despite having an ocean between them) and similar fossil records, … When the two meet, the denser oceanic plate is pulled beneath the continental crust.

What evidence is there for plate tectonics quizlet?

What are the five main pieces of evidence for the Theory of Plate Tectonics? Magnetic striping, Age of the ocean’s crust rocks, Coral islands, The position of ocean trenches and the locations of earthquakes and volcanoes.

Why do continents move quizlet?

Thermal energy generated in the Earth’s core causes the tectonic plates on the Earth’s surface to move. This movement occurs due to convection currents deep in the Earth.

What evidence supports plate tectonics quizlet?

Rock and fossils found in South America match those found in Africa, although there is an ocean in between. This also indicates that the two continents were once joined. Other evidence of plate tectonics include Seafloor spreading, which involves the creation of new crust at divergent plate boundaries.

Which of the following is evidence supporting plate tectonics and continental drift?

One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

Which statement explains the movement of these lithospheric plates?

The plate tectonics theory explains that the plates are moving slowly along the Earth’s surface due to the convection currents in the mantle. Over time, the movement of plates results in the changes in the distribution of organisms, and the formation of volcanoes and mountain ranges, as well as earthquakes.

What do we see in Earth’s topography that shows evidence of plate movement?

Ocean topography also provided evidence of plate tectonic theory. … Geoscientists later identified the mountainous features as the mid-oceanic ridges (MORs) where new plates form, and the deep ocean trenches as subduction zones where plates descend into the subsurface.

Which of the following provides evidence for the existence of Pangea?

The rock formations of eastern North America, Western Europe, and northwestern Africa were later found to have a common origin, and they overlapped in time with the presence of Gondwanaland. Together, these discoveries supported the existence of Pangea.

What is the first lines of evidence suggesting the existence of plate tectonics?

One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. It suggested that those land areas had in the past been connected.
