What are the similarities and differences between a convergent and a divergent zone?
In summary the Divergent and Convergent plate margins have similar and different topographical features that would have been formed or is still forming as a result of tectonic plate movement. The similarities are volcanoes and mountain ranges while the differences are rift valleys and ocean trenches.
What happens at a divergent boundary?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. Two plates sliding past each other forms a transform plate boundary.
Which feature is most likely found at a divergent boundary?
In geological studies, a divergent boundary can be described as a linear feature which arises due to plate tectonics which are being pulled apart from each other. Hence, fault-block mountains are most likely to be seen in a divergent boundary.
What type of boundary is illustrated in Figure 9 1?
Convergent plate boundary
Which type of fault is a transform boundary?
Transforms are strike-slip faults. There is no vertical movement—only horizontal. Convergent boundaries are thrust or reverse faults, and divergent boundaries are normal faults. As the plates slide across from each other, they neither create land nor destroy it.

Which of the following is a geographic example of a transform boundary?
The most famous example of this is the San Andreas Fault Zone of western North America. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Another example of a transform boundary on land is the Alpine Fault of New Zealand.
What is the thin rocky outer layer of Earth?
Cutaway Earth The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth.
What are the three main parts of the geosphere?
The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron.
What are examples of Geosphere?
Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans. They also include the mountains, minerals, lava and molten magma from beneath the earth’s crust. The geosphere undergoes infinite processes constantly and that, in turn, modifies other spheres.
What are the four main parts of the geosphere?
The geosphere has four layers: the crust, the mantle, the inner core and the outer core.
Is natural gas a part of the geosphere?
Deposits of these fuels formed millions of years ago, when plants and animals—all part of the biosphere—died and decayed. At that point, their remains were compressed within Earth to form coal, oil, and natural gas, thus becoming part of the geosphere.
Why is it called natural gas?
It’s often called ‘natural gas’ because it’s a naturally occurring hydrocarbon (a particle made of hydrogen and carbon atoms). It’s colourless and consists mainly of methane, which is the simplest type of hydrocarbon.
When did natural gas become popular?
The first commercialized natural gas occurred in Britain. Around 1785, the British used natural gas produced from coal to light houses and streets. In 1816, Baltimore, Maryland used this type of manufactured natural gas to become the first city in the United States to light its streets with gas.
How much natural gas is left in the world?
As of January 1, 2020, there were an estimated 7,257 trillion cubic feet (Tcf) of total world proved reserves of natural gas.
Will natural gas ever run out?
Assuming the same annual rate of U.S. dry natural gas production in 2019 of nearly 34 Tcf, the United States has enough dry natural gas to last about 84 years. The actual number of years the TRR will last depends on the actual amount of dry natural gas produced and on changes in natural gas TRR in future years.
