What is the relationship between the earthquakes positions and tectonic plates?
Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
Where do earthquakes occur in relation to the continents?
Most earthquakes occur along the edge of the oceanic and continental plates. The earth’s crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.
What is the link between Earth’s structure and earthquakes?
The structure of the Earth Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth. As seismic waves pass through the Earth, they are refracted, or bent, like rays of light bend when they pass through a glass prism.
What is the relationship between continental drift and earthquakes?
According to this theory, Earth’s crust is broken into roughly 20 sections called tectonic plates on which the continents ride. When these plates press together and then move suddenly, energy is released in the form of earthquakes.
What is the relationship between locations of earthquakes and plate tectonics quizlet?
What is the relationship between locations of earthquakes and plate tectonics? A. Earthquakes frequently happen where landmasses are on the boundary between two plates.
Where do the most earthquakes happen?
Pacific Ocean
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
What are the 3 main layers of the earth?
The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core.
How does movement of Earth’s plates cause earthquakes quizlet?
– When plates move, great force is exerted on the rocks of Earth’s crust. The rock will bend and stretch only so far before they break and faults, or huge cracks in the crust, form. When rocks begin to scrape past each other at a fault, an earthquake happens.
What is the relation between volcanic activity and plate tectonics quizlet?
spreading or sinking plates at plate boundaries interact with magma within the Earth and the volcanoes are constructed around the volcanic vent where lava and materials extrude onto the surface. You just studied 11 terms!
What country has the most tsunamis?
Indonesia
Where do tsunamis most often occur in the world? Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones.
