How Are Plate Tectonics And Continental Drift Related?


How do tectonic plates interact?

Tectonic plates can interact in one of three ways. They can move toward one another or converge move away from one another or diverge or slide past one another a movement known as transform motion. All plate margins along which plate movement is occurring have one thing in common—earthquakes.

What do the continental plates consist of?

Continental crust is composed of granitic rocks which are made up of relatively lightweight minerals such as quartz and feldspar. By contrast oceanic crust is composed of basaltic rocks which are much denser and heavier.

What causes tectonic plates to move?

Tectonic shift is the movement of the plates that make up Earth’s crust. … The heat from radioactive processes within the planet’s interior causes the plates to move sometimes toward and sometimes away from each other. This movement is called plate motion or tectonic shift.

What does the theory of plate tectonics explain that continental drift theory could not explain?

Plate tectonics explains why Earth’s continents are moving the theory of continental drift did not provide an explanation. … Scientists have found that the planet’s continents will likely again be joined together in about 250 million years. Researchers have dubbed this future continental configuration “Pangaea Proxima.”

What is the theory of plate tectonics?

The theory of plate tectonics states that the Earth’s solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. Oceanic and continental plates come together spread apart and interact at boundaries all over the planet.

How plate tectonics are related to earthquakes and volcanoes?

As plates move they get stuck in places and enormous amounts of energy build up. When the plates finally get unstuck and move past each other the energy is released in the form of earthquakes. Earthquakes and volcanoes are common features along tectonic plate boundaries making these zones geologically very active.

What are plate tectonics quizlet?

plate-tectonics. the theory that states that pieces of Earth’s lithosphere are in constant slow motion. convection currents. currents in the mantle that cause the movement of Earth’s plates.

What is the difference between plate tectonics and plate boundaries?

The difference between plate tectonics and plate boundaries is that one is a scientific theory while the other is a physical property of tectonic

How the continental drift theory seafloor spreading theory and plate tectonic theory are related to one another?

Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. … Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ridge push. See also which bond or interaction would be difficult to disrupt when compounds are put into water

Which of these is a result of plate tectonics?

The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig.

How are volcanoes and earthquakes related?

They are both caused by the heat and energy releasing from the Earth’s core. Earthquakes can trigger volcanic eruptions through severe movement of tectonic plates. Similarly volcanoes can trigger earthquakes through the movement of magma within a volcano.

How Are Plate Tectonics And Continental Drift Related?

Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener which he called continental drift. … But the continents actually are shifting very slowly relative to one another.Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener Alfred WegenerThe theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth sometimes plowing through oceans and into each other. › continental-drift

How does continental drift happen?

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 tectonics.

How are continental drift and plate tectonics related quizlet?

Continental drift believes that the continents moved because the magnetism of the sea floor. Plate tectonics believes that the lithosphere & the asthenosphere of the continents caused them to move.

Which geologic processes are associated with plate tectonics?

The occurrence of earthquakes and volcanoes the distribution of different rock types and the Rock Cycle as well as the processes of mountain building continental rifting and seafloor spreading can be concisely explained by plate tectonic processes.

Does the theory of plate tectonics explain where volcanoes are located and why they are located in those places?

The theory of plate tectonics explains most of the features of Earth’s surface. It explains why earthquakes volcanoes and mountain ranges are where they are. It explains where to find some mineral resources. Plate tectonics is the key that unlocks many of the mysteries of our amazing planet.

What is best explained by plate tectonics quizlet?

Which process is best explained by the Theory of Plate Tectonics? … Tectonics plates divide the earth’s outer layer (lithosphere). Under the lithosphere is the asthenosphere where the differences in temperature and pressure cause the plates to move.

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.

How the movement of tectonic plates creates volcanic landforms?

Volcanoes and ridges are landforms that are created by the movement of tectonic plates. Some volcanoes are formed when the plates pull apart under the ocean. … Other volcanoes are created when a tectonic plate slides under another. As the bottom plate is heated up by the Earth’s hot mantle a material called magma forms.

Does each tectonic plate move?

The plates make up Earth’s outer shell called the lithosphere. … 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.

How is plate tectonics supported by the apparent fit of the continental coastlines?

This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift . However we now know that it is not just the continents that move so a more correct term is plate tectonics .

Which is a type of tectonic plate boundary quizlet?

A convergent boundary is the boundary between two colliding plates. A divergent boundary is the boundary between two plates that are pulling away from each other. A transform boundary is the boundary between two plates that are sliding past each other.

What caused continental drift quizlet?

a current caused by the rising of heated fluid and sinking of cooled fluid. The earth’s crust and upper mantle are made of huge plates slowly drifting because of convection currents in the mantle.

What are the two main factors that cause the movement of tectonic plates?

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.

How do plates move where convection currents are sinking?

Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises cools and eventually sink down. As the cooled material sinks down it is warmed and rises again.

Is continental drift the same as plate tectonics?

The main difference between plate tectonics and continental drift is that plate tectonics describes the features and movement of Earth’s surface in the present and in the past whereas continental drift describes the drifting of Earth’s continents on the ocean bed. See also what is the theme of divergent

What is the continental drift quizlet?

The hypothesis that states that the continents once formed a single landmass broke up and drifted to their present locations. …

Why was the continental drift theory replaced by plate tectonics?

Wegener’s theory has now been replaced by the theory of plate tectonics – an extension of continental drift theory that suggests continents migrate due to the movement of the tectonic plates on which they lie.

Which of the following best explains the difference between continental drift and plate tectonics?

Which of the following best explains the difference between continental drift and plate tectonics? Continental drift describes the motion of Earth’s continents only plate tectonics describes the motion of the crust beneath Earth’s oceans as well.

What is the relationship between continents and plate tectonics?

For billions of years plate tectonics built and fragmented supercontinents—land masses made of multiple continents merged together. The plate tectonic cycle begins with a supercontinent balanced by a super ocean. Plate movement slowly breaks apart the supercontinent.
