Tectonic plates are huge pieces of Earth’s lithosphere, or outer shell, that shift on top of the Earth’s mantle, or the rocky inner layer of Earth. Plates can be made up of oceanic lithosphere or continental lithosphere. In total, Earth’s lithosphere is composed of seven major tectonic ...
When tectonic plates are pushed apart in one area, something has to give elsewhere. The leading edges of the growing plates collide, and this may result in several outcomes. In some instances, one plate may grind along the edge of another, as the Pacific plate and the North American plate ...
The boundaries of the benthic zones are difficult to define. The watery upper part of the benthic zone is separated from the water above by the... Learn more about this topic: Aquatic Ecosystems: Characteristics & Definition from Chapter 14/ Lesson 2 53K Aquatic ecosystems are composed of a ...
Layers of the Earth: The Earth consists of several layers that sit on top of one another. The outermost layer is the lithosphere, and this layer is made from tectonic plates. Answer and Explanation:1 The lithosphere is broken into several tectonic plates that are composed of hard rocks. This...
The different types of volcanoes are cinder cone, composite, shield, and lava volcano. The classification of volcanoes is based on the time of occurrence, and they are active, dormant, and extinct. Click here to learn about types of volcanic eruptions
What is continental crust composed of? Silicate Minerals: A mineral is a hard, inorganic substance (element or compound) found in nature. A silicate mineral contains silicate, which is an ion made of one silicon atom and one or more oxygen atoms. Silicate minerals are a major part of the ...
The theory of plate tectonics argues that Earth's outer layer—the crust—is composed of large platelike sections of solid rock. These plates essentially float on weaker layers of partially melted rock in the mantle below. Scientists believe that convection circulation within the mantle helps contin...
Volcanic pipes, particularly those composed of kimberlite or lamproite, are primary sources of diamonds. The high-pressure conditions deep within the Earth's mantle are conducive to diamond formation. These diamonds are then transported to the surface by the eruptive process that creates the pipe, ...
The biosphere is the global ecosystem, which is the zone of life on Earth. It is composed of three different parts, which are abiotic, biotic and energetic components. The biosphere is where life exists. Answer and Explanation: Become a Study.com member to unlock this answer!Create your acco...
What are the 4 plate boundary types? Tectonic Plates and Plate Boundaries Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. ... Divergent boundaries – where two plates are moving apart. ... ...
