What are the crustal features?
Crustal features. include those expressed on the surface, (such as mountains, rivers, and lakes) as well as those not as visible (such as volcanic feed pipes, earthquake fault lines, Geological formations, and aquifer formations.)
What are the 3 tectonic plate movements?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What are the four movements of the tectonic plates?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
What are divergent crustal features?
Mid-ocean ridges are crustal features that occur at a divergent plate boundary. A divergent plate boundary occurs when convection cells cause two adjacent plates to move in opposite directions away from one another. Include long mid-ocean rises as well. These are similar to ridges, just not quite as big.
What crustal features are created at divergent boundaries?
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
How does plate tectonics explain the movement of the earths crust?
Plate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig.
How are the different types of crustal plates related?
The crust of the earth is separated into ten major plates and a few smaller ones. These plates interact with each other along their edges as they shift position on the earth’s surface. The motion of crustal plates is described as the relative motion between two plates where they touch; this motion fits into one of three categories:
What kind of features form along plate boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Why are geologists interested in crustal plates and volcanoes?
This theory explains how crustal plates move around the surface of the earth, and it allows geologists to find explanations for geologic events such as earthquakes and volcanoes, as well as the many other processes that form, transform, and destroy rocks.
