Which of the following pieces of evidence supports the plate tectonic theory? What evidence supports the plate tectonic theory?

Heat and gravity are fundamental to the process

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 does plate tectonic theory predict about the distribution of volcanoes and earthquakes?

What does plate tectonic theory predict about the distribution of volcanoes and earthquakes? They should be evenly distributed throughout the earth. They should occur primarily along plate boundaries.

Which of the following observations about landforms best supports the theory of plate tectonics?

Which of the following observations about landforms best supports the theory of plate tectonics? Impact craters have been found both on dry land and on the ocean floor. As lava cools on Earth’s surface, it forms a variety of igneous rocks. Volcanoes are distributed randomly on every continent.

Which theory provides the most acceptable cause of plate movement?

Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. The heat source is thought to be the decay of radioactive elements.

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.

What type of evidence for the plate tectonic theory is provided when scientist discovered that the magnetic field reverses polarity?

This further provided evidence for plate tectonics. More evidence came when scientist examined the sea floor and saw that there were reversals of polarity of Earth’s magnetic field that was in a striped pattern. The strips of polarity reversal were mirror images on each side of the mid- ocean ridge.

What are 6 pieces of evidence that support 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 evidence supports the idea that all the continents were once joined together?

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

How does the formation of the Hawaiian Islands support the theory of plate tectonics?

The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

How do hotspots and the plate tectonics theory account for the different ages of the Hawaiian island?

How do hot spots and the plate tectonics theory account for the fact that the Hawaiian Islands vary in age? … According to the plate tectonics theory, as a plate moves over a hot spot, magma often penetrates the surface, thereby generating a volcanic structure.

What are the 3 tectonic plate movements?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.

Do these findings allow the inside out model to be elevated to a scientific theory why or why not 3 points?

Do these findings allow the inside-out model to be elevated to a scientific theory? Why or why not? No, because data from one volcano is not sufficient to show that ocean water was produced by volcanoes. … The theory of plate tectonics was developed with the contribution of scientists from many different disciplines.

How are oceans directly affected by increased carbon dioxide concentrations in the atmosphere quizlet?

Oceans absorb large quantities of carbon dioxide from the atmosphere. Oceans currents drive surface winds, allowing for atmospheric heat exchanges. Oceans absorb water vapor from the atmosphere and release oxygen, making air breathable. Oceans absorb large quantities of carbon dioxide from the atmosphere.

What data helps provide support for the plate tectonic theory quizlet?

Also, the theory of seafloor spreading helps to support the theory of plate tectonics because it explains how the continents move. Furthermore, a GPS satellite in space can be used to measure how far and how fast the continents move each year.

Which of the observations supported and helped develop the plate tectonic theory?

how do observations of earthquakes and volcanic activity support the theory of plate tectonics? the theory of plate tectonics helps explain this pattern because the earthquake and volcano belts mark the location of plate boundaries.

How did the theory of plate tectonics prove the theory of Alfred Wegener?

Alfred Wegener in Greenland. Plate tectonics is the theory that Earth’s land masses are in constant motion. … Wegener observed that the continents of South America and Africa looked like they would fit together remarkably well—take away the Atlantic Ocean and these two massive landforms would lock neatly together.

How did Sonar help prove plate tectonics?

Sonor showed the mid Atlantic ridge dividing the plates like the north Atlantic from the European plate. This provides evidence for Wegener’s theory of Continental Drift.

How Do We Know Plate Tectonics Is Real?

Evidence of Plate Movements

FAQs about which of the following pieces of evidence supports the plate tectonic theory?

1. What evidence supports the theory of plate tectonics?

The theory of plate tectonics is supported by the fact that the Earth’s crust is made up of a series of plates that are constantly moving. These plates can collide with one another, causing earthquakes and volcanoes.

2. Which of the following pieces of evidence supports the plate tectonics theory quizlet?

The plate tectonics theory quizlet is supported by the fact that the Earth’s crust is broken into about a dozen large pieces called plates. The plates are always in motion, and because they are always in motion, the Earth’s surface is always changing.

Every day, we see new evidence that supports the plate tectonic theory. What do you think the answer is? Let we know in this section below!
