What Are Plate Tectonics And Ocean Currents Influence Climate Change?

The Earth is a very detailed planet; there are many actions going on at once on this planet. The Earth has many boundaries, plates. and layers. The plates beneath our feet mold the world we live in. While very slowly, the plates are indeed moving. There are a few variations to the plates; they have different directions in which they move in relation to separate plates. These changes in plate movement have different side effects, from ocean trenches to miles of mountain ranges.

Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt. (Pitman, W.C., 2007)

Plate tectonics is a theory that Earth’s crust is broken up into plates that float along the mantle. The plates act like a broken egg shell around the yolk or mantle, outer core, and inner core. Scientist Alfred Wegener didn’t have a scientific reason to explain how the continents moved. These plates are moving very slowly and in a very, very, very long time, Earth will look different than what the continents look like now. The Nazca Plate is moving southeast and will cause a collision with the South American Plate.

The Earth is always changing because of plate tectonics. Plate tectonics describes the behavior of earth's out shell, with pieces bumping and grinding each other about. Most of the world's active volcanoes are located along or near the boundaries between shifting plates and are called plate-boundary volcanoes. The Hawaiian Islands are one of the best examples of an intra-plate volcanic chain. They are developed by the northwest-moving Pacific Plate passing over an inferred hot spot that inmates the magma generating and volcano-formation process. The Ring of Fire in parts of the Pacific Ocean contain many active volcanoes which Mt. St. Helens is a part of. The zone along plate boundaries are the most geologically active regions on Earth.

What makes Earth’s plates move? convection currents in the mantle is what moves the plates.

On our home planet, there are eight major tectonic plates- African, Indo-Australian, Eurasian, Antarctic, North American, South American, Nazca and the Pacific. These plates are all separate and floats completely independently upon the Earth's mantle, which is much hotter than the crust of the planet. The locations where these plates meet each other are usually places that are extremely prone to large earthquakes and volcanic

These plates, along with several smaller ones, are called the lithospheric plates, because they are part of the lithosphere, which is the outermost part of the Earth's shell. . The plate boundaries can be three different types: divergent, transform or subduction. Divergent boundaries occur when the plates are moving away from each other. Transform boundaries are where the plates slide against each other with a back and forth motion. Subduction boundaries occur when an oceanic plate moves under a continental plate. This movement causes volcanic activity and earthquakes. (This boundary is also called convergent.) This activity is always happening, because the plates are constantly in

The different tectonic plates rest on the mantle, a very hot layer of earth that is directly beneath the crust. There are seven major tectonic plates, their names are The Pacific Plate, The North American Plate, The Eurasian Plate, The African Plate, The Antarctic Plate, The Australian Plate, and The South American Plate. In addition to these major plates there are also many smaller tectonic plates that make up parts of the Earth's crust. When the boundaries between plates shift, this causes earthquakes. There are three types of movements that cause earthquakes. Divergent is when the plates move away from each other, Subduction is when one plate moves underneath another, and Transform is when the plates grind against each other. The lithosphere is another name for earth's crust and mantle, it is made up of all the tectonic

Answer the following questions using complete sentences. Each question is worth 4 points. 1. Describe four factors that influence ocean currents. Four factors that influence ocean currents are the Coriolis Effect, the climate, upwellings, and water density.

Earth has many tectonic plates which made out the seven continents. even today there are tectonic plates that are shifting. Some say that California is shifting away from the United States. Although, Earth started out with one continent called Pangaea. There are three major types of tectonic plate boundaries. The first one is divergent, divergent is when the plates move apart from one another. The second one is subduction, subduction is when the oceanic plate moves under a continental plate. Subduction mostly causes the most violent earthquakes and volcanic activity. The last major type of boundary is transform, transform is when the plates slide back and forth against one another. Plates that are located in the Lithosphere are North America, South America, Africa, Europe, Asia, India, Antarctica, Australia and the Pacific

There has been a rise of 0.68 degrees celsius since 1950. That is not a lot, but that has been an average rise in temperature; places can be even hotter. Temperatures in the polar regions have increased by double of that. As the world warms up, so does the ocean. Marine organisms are very sensitive, including coral. Not only that, photosynthesis can not be done if the ocean temperature is too high. Phytoplankton is at the bottom of the food chain. It makes food by photosynthesis. Animal plankton eat the phytoplankton, which gets eaten by bigger animals, which get eaten by fish, and so on and so on. So, if the ocean warms up, photosynthesis cannot be done, and everything in the food chain dies off. Fish becomes less common. Nearly everyone likes

Plate tectonics occur not only just on Earth, but on other planets in the galaxy as well, such as Venus, Mars, and ancient Mercury. Since there are several planets in the Milky Way that have plate tectonics, it is questionable about if size is a key factor in the likelihood of tectonics on foreign planets. Vol-canoes, mountains, ocean ridges, earthquakes, and tsunamis all would not be possible without the movement of the Earth’s tectonic plates. Dependent upon heat for movement, tectonic plates are one of the victims of Earth’s active life. Since the Earth is not static in movement, landforms are moved and shifted slowly but surely each day. It is questionable if hydration and planet size are significant factors in the likelihood of plate tectonics on super-Earths.

The atmosphere can be described as chaotic, with the changes in climate being as a result of natural or anthropogenic activity as stated by the IPCC (2007). The external changes on the climate are due to changes in the incoming solar radiation and how this differs through time and differing locations. Volcanoes, greenhouse gases and industrial effects all fall under the internal effects as these happen on the earth itself. Before the industrialisation period, it was believed that the main factors affecting the climate were due to solar output and volcanic eruptions. However, due to increased emissions and aerosols the processes of industry have become the more dominant forcing factor.

The answer is yes. During this quarter we learned a lot about global warming and its disturbing effects on ocean and climate. Ocean currents that are caused by thermohaline circulation are affected by global warming due to glacial melting in Antarctica and Greenland which cause abundant freshwater input into thermohaline circulation and thus mixing of freshwater with saline water causes the current to slow down and even possibly to shut down, for example, ocean current such as Gulf Stream. Likewise, global warming causes tidal range change due to sea level rise, which is caused by the same factor of glacial melting. NOAA suggests that “tidal datums must be updated at least every 20-25 years due to global sea level rise.” According to Doeke

     Now that we are aware that global warming is influencing our world’s oceans, we must look at the affects that it is having. I did not find any positive affects of global warming on the oceans. It is sad to say, but I was left with only the negative. One of the effects that warmer temperatures have on the oceans is that they disrupt the ocean circulation rate (Pearce, 1996). As I previously mentioned, oceans must maintain all of its characteristics properly. Warmer temperatures in the atmosphere affect circulation rates in the oceans. If circulation rates in the oceans are altered, then everything in the oceanic environment becomes changed. The oceanic currents become affected, as well.
