What are some examples of crustal features?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.
What are the 7 crustal plates?
how many tectonic plates are there? There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
What are crustal pieces called?
The Earth is made up of roughly a dozen major plates and several minor plates. Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another.
What’s a crustal feature?
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 crustal features are created from divergent plate boundaries list three?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
What is a crustal plate?
Definitions of crustal plate. a rigid layer of the Earth’s crust that is believed to drift slowly. synonyms: plate. type of: Earth’s crust, crust. the outer layer of the Earth.
What are the 2 types of crustal plates?
The two types of tectonic plates are continental and oceanic tectonic plates.
What two features are commonly found at divergent boundaries?
The features most commonly associated with divergent boundaries between tectonic plates are rift valleys, ocean ridges, fissure volcanoes, and…
How are the ocean crusts moving?
Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading. As it moves, it becomes cooler, more dense, and more thick. Eventually, older oceanic crust encounters a tectonic boundary with continental crust. In some cases, oceanic crust encounters an active plate margin.
