Boundary Waters

from. They’re most commonly located near ocean ridges because that’s where the most tectonic plate movement happens therefore, more eruptions. Depending on the depth at which the volcano is, vapor clouds may be visible but usually only in shallow waters. There are two big types of volcanic eruptions, huge lava pockets that release really slowly and and bunch of little lava pockets that burst super fast. There has been a study conducted so that scientists are able to differentiate the types of eruption

mantle. The boundaries between the plates are known to serve as an important mineral resource. Three types of tectonic plate exist: convergent, divergent and transform boundaries. A convergent boundary represents two plates moving towards each other mostly forming a subduction. When two plates move away from each other, a divergent boundary is formed. In transform boundaries, the plates move laterally past each other (Mission, 2016). Within the mid-ocean ridges forming a divergent boundary, a zone of

under tectonic plates An earthquake occurs when tectonic plates slide against, under, over or past each other. Tectonic plates are plates that are broken up like a jigsaw that are located in the outer layer of the Earth (see source 2). All of the water and land on the Earth sit on tectonic plates. The Earth is made up of eight major plates, Australia is located on the Indo-Australian Plate. These plates are constantly moving beneath us but the movement is too slow for us to notice and feel. The energy

address. Geodesists and surveyors use datum to create starting or reference points for floodplain maps, property boundaries, construction surveys, levee design, or other work requiring accurate coordinates that are consistent with one another.

Volcanoes have been a part of Earth’s geologic timescale for as long back as we can look. The people of ancient Greece believed the fumes were the fiery breath of a monster, held captive under a mountain by the almighty God, Zeus. The Romans were convinced the God of Blacksmith, Vulcan, was working diligently in his personal forge crafting the weapons of the Heavens. Some civilizations even feared volcanoes, with the idea that they were the passage way to the underworld, a hell here on Earth. If

as well. Different types of volcanoes are created at plate margins due to the viscosity of the lava. The two main types of volcanoes are composite volcanoes and shield volcanoes. Composite volcanoes are generally formed at destructive plate boundaries as high viscous lava is produced as less dense oceanic crust is

with two major ski-fields and only glaciers on its slopes. Creation Believe it or not, both surface features are active volcanoes. Lake Taupo a caldera, and Mt Ruapehu a stratovolcano. These volcanoes were formed because TVZ is a convergent plate boundary where the Pacific (Oceanic) plate which is more dense ,is getting subducted under the Australian (Continental) crust which is less dense. This is being driven by a force called convection which happens in the asthenosphere which is fluid. It is when

According to the theory of plate tectonics there is constant motion in the lithosphere which causes the many plates lying upon it to move relatively to one another due to convection currents. There are 3 boundaries where volcanic and seismic events, but not limited to, occur. The constructive plate boundary is where 2 plates, such as the North American plate and the Eurasian plate move apart causing sea-floor spreading and volcanic activity – when the less dense basaltic lava from the asthenosphere rises

Water from the south then flowed in over time, thus forming the evaporites now found along the coastlines there. (Lois Van Wagner, 2013)(Figure 5) However, Wegener believed that only the continents were moving and they plowed through the rocks of the ocean
