‘Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid.’ Discuss the extent to which you agree with this statement. (40 marks) Over the years proceeding the birth of the theory‚ increasingly convincing evidence has been gathered for proof of the theory of plate tectonics. In 1912‚ Alfred Wegner proposed the theory that continents are sat upon tectonic plates and that these plates are slowly drifting around the Earth (continental drift).

Research Paper The ocean is one of‚ if not‚ the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface‚ the ocean is our planet’s largest habitat‚ containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes‚ oceans are subdivided into separate zones: intertidal‚ pelagic‚ abyssal‚ and benthic. All four zones have a great diversity of species. The

The Structure of the Earth and Plate Tectonics Structure of the Earth Mantle • The Earth is made up of 3 main layers: Outer core Inner core – Core – Mantle – Crust Crust The Crust • This is where we live! • The Earth’s crust is made of: Continental Crust Oceanic Crust - thick (10-70km) - buoyant (less dense than oceanic crust) - mostly old - thin (~7 km) - dense (sinks under continental crust) - young How do we know what the Earth is made of? • Geophysical surveys: seismic‚ gravity‚

Dear Coach Williams‚ I have been on a boat in the ocean for 3 months now. I learned about three species and several plants. I found incredible facts about the ocean. The ocean covers 71% of the earth’s surface and contains 97% of earth’s water. Less than 1% of the earth’s water is freshwater. The other 2-3% is contained in glaciers and ice caps. Also‚ 99% of the living space is contained by the ocean and it holds 320 million cubic miles of water. The Pacific ocean has the nickname “peaceful sea”

land masses are moving independently of each other‚ thus‚ may actually be parts of separate plates. The Philippine Sea plate is found east of the Eurasian plate. It is the bedrock of the major islands of the Philippines‚ Indonesia‚ Taiwan‚ and the Marianas. Formation of Island Arcs Below these plates is the mantle‚ a very hot section of the Earth where rocks are at the point of or is actually melting. These hot and molten rocks stream steadily making the plates above it move about. The plates move

Deep Exploration: Argumentative Essay Have you ever thought of what was at the bottom of the ocean‚ or far in space? Have you ever wondered what kinds of creatures lurk in the Mariana Trench? Many of these questions can be answered if you support one simple thing: Deep Exploration! Deep Exploration would possibly allow us to find a new species‚ or even a species we thought was extinct! It’s a risky business‚ but think of all of the knowledge we would gain from it! Almost all of our technology

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

Geology 101 Research Paper Earthquakes & Tsunamis The Earth is 71% oceans. There can be no surprise then that the oceans affects human existence every day. Oceans are a source of economy‚ leisure‚ and sustenance. They are also a powerful force to be respected and studied. When the oceans unleash their power and volume in the form of tsunamis the effects are almost always devastating for mankind. These events have changed the course of life on earth more than once. Tsunamis can be triggered
