Essays on Magma

Around the world, there are roughly 1500 potential active volcanos. Most of these volcanoes are around the Pacific Rim also referred to as ‘Ring of Fire.'

Volcanic ash has minerals within it when incorporated into the soil; it adds nutrients.

Volcanic mountain slopes are steep in nature. It makes it inaccessible to both animals and human beings. It provides habitat for rare plant and animal species away from human manipulation. Gases that erupt from volcanoes provide water and atmosphere. Regardless of the slow processes involves I making them it is significant over an extended period. Most volcanoes exist on the brink of tectonic plates. Amongst the tectonic plates, the largest is the Pacific ...

Question 1 Tectonic plate motion refers to the movement of continental and oceanic plates from one place to another due to the effect of forces that generally act on these plates. These movements cause some effects to the surrounding environment and even to the earth surface in general. A scientist by the name of Wegner had earlier on formulated a theory that instituted some of the facts and evidence backing this presence of continental drift that had happened some time back in history (Runcorn, 2013). Furthermore, the critical evidence in support of continental drift is the jigsaw fitness of ...

Hawai'i was the 50th state to join the USA. It comprises 132 islands and is said to be the home of volcanic islands. These islands reside in the Central Pacific Ocean. Moana Loa is one of the top most active volcanoes that had formed the island of Hawaii in the ocean (Networks, 2016). The movement of plate tectonics has resulted in the volcanic eruption and, however, the volcano towering and presence of valleys had a significant impact on the economic value.

Theory of plate tectonics

Plate tectonics theory explains that upper layer of the earth’s surface is segregated into various plates that ...

The continental plate in the eastern part of Asia is composed of various volcanoes and tectonic movements. Most of the volcanic rocks in this region are composed of alkali basalts with signs of continental contamination. There are various models that explain the region’s magmatic evolution. The two most common models used to explain the movements refers to the surficial processes and the other one refers to the deeper processes associated with the Pacific ocean plate. These two processes are antithetic and may hay happen subsequently. The volcanism can be traced by tomographic imaging that can be directly associated ...

The continental landscape features are reflected with analogous features on the ocean basins. Plains, Plateaus, volcanic cones, rolling hills, mountains, and valleys are found underwater in the oceans just like on land. However, research reveals that the largest mountains found beneath ocean waters are higher as compared to those on the continent. Also, the plains found under water are more extensive and flatter than those on the dry land.

The Shape of the Land

The ocean basins can be referred to that surface of the Earth that extends towards the sea from the margins of the continent. Ocean basins are usually submerged in the ...

An earthquake is any seismic event that causes seismic waves. These can be caused by human activity or natural causes. For example, fracking often causes earthquakes which are human caused. Earthquakes often shake or displace the ground or surface of the earth near the epicenter and if the displaced earth is under the ocean, it will usually cause a tsunami. Most earthquakes are caused by geological faults but they can also be caused by landslides, mine blasting, and volcanic activity. Earthquakes are measured by overserving seismometers that are set up across the globe in strategic places for ...
