Why Are Oceans So Salty?

As a tectonic plate slides into the mantle, the heat releases fluids trapped in the plate. Seawater and carbon dioxide, rise into the upper plate and can partially melt the overlying crust, forming magma. And magma most likely means volcanoes are around.

The land is uplifted crust blocks that form parallel ranges but surface water doesn’t run to the ocean. Instead, it evaporates over time leaving a salt flat.

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

5) Sources of the salt found in water: Earth’s crust, Earth’s atmosphere, gases, magmatic material and volcanic water. The input regulated by providing ions and recycling materials.

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

Located on the fault are sediments, amongst them are turbidites. Turbidites are areas of sediment are deposited in the deep ocean. There are also oceanic deposits, volcanic ash, siliceous oozes, and primary dolomites, which are a formation of

These blasts of minerals can be as high as a three-story house and will have an effect on the way the land is shaped on the surface. Shrimp thrives on the nutrients from these volcanic blasts and have created their own communities. Huge volcanoes underwater can be unbelievable high and create either tall cliffs or valleys on the ocean floor. Currents caused by these volcanoes will move nutrients and organisms to different depths and/or locations. These cliffs are home to many communities such as colorful corals and whipcords, which can catch nutrients from the currents like most communities

A volcano is a weak spot in the crust where molten material, or magma, comes to the surface. In a volcano there is a magma chamber, pipe, vent, lava flow, and craters. A magma chamber is the pocket where magma collects under or below a volcano. The pipe of a volcano is the long tube in the ground that connects the Earth's surface to the magma chamber. A vent in a volcano is where the molten rock and gas from the volcano leave through an opening. The lava flow is a certain area that is covered by lava that is coming out of the vent. Lastly, a crater is a bowl shaped area that is formed at the top of the volcano.

A- Salt water is more dense than fresh water, and therefore sinks under fresh water - which is exactly what happens in estuaries, which are areas near the mouth of a river where fresh water and salt water do mix.

They were smart and they did the smartest thing that they could think of. They mixed all of the salt with all the water, and they made salt water. Then they picked a HUGE place to distribute all of it and there is now salt water because of that crazy newt,

According to Middlemost (1988)’s basic definition, magma is a heated rock-forming substance that is created within a planet and exists only below Earth. When magma escapes to the Earth’s surface and is extruded, they are known as lavas. Grotzinger and Jordan (2010) suggests that magma mainly comes from the asthenosphere- the upper part of the mantle.

The cone formed around the vent consists of layers of lava, ash and agglomerate. The agglomerate usually falls back to the vent.

Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.

increases. When carbon dioxide dissolves at the ocean’s surface it reacts with the water and then

A volcanic vent is a an area in the ocean where seawater seeps into small cracks. These cracks go far into the earths crust, the water can get a temperature of 750 degrees Fahrenheit.
