What are some questions that answered by plate tectonics?
Plate tectonics test questions
- Which is the correct order for the layers of the Earth?
- Which is the thinnest layer of the Earth?
- What is slab pull?
- Where are earthquakes created?
- Which is lighter: oceanic or continental crust?
- How does a collision zone differ from a destructive plate boundary?
What are the two main evidence of plate tectonics?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
What drives plate tectonics?
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 are the evidence of plate tectonics?
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.
What do you know about plate tectonics?
Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere , since tectonic processes began on Earth between 3 and 3.5 billion years ago. The model builds on the concept of continental drift,…
What do tectonic plates do?
Tectonics, also known as plate tectonics, is the theoretical understanding of how the surface of the earth is constantly shifting. According to the best understanding of science, giant tectonic plates are always moving very slowly as the Earth generates new crust and reclaims old crust. The effect has often been compared to a giant conveyor belt.
How are earthquakes connected with plate tectonics?
Most earthquakes occur as the result of the sudden movement along a fault line between two adjacent tectonic plates. The movement of the plates is not always smooth. The plates “catch” on each other due to friction. Since the plates are always moving, these catches cause energy to build up along the fault line.
