continents had once been connected‚ but he was the first to present extensive evidence from several fields. He was subsequently proved right‚ although he was wrong in one respect; the continents don’t drift on their own‚ they move as part of much larger "plates" of the Earth’s surface‚ much of which is ocean floor. Wegner’s hypothesis stated that Earth’s continents were once joined in a single landmass and gradually moved or drifted apart. Yes‚ that and he also provided information showing it‚ such as fossils

Lesson 1.06 1) Explain the relationship between continental drift and the formation of the Earth’s Oceans? -The relationship between continental drift and the formation of the Earth’s Oceans stems from plate movement that occurred on Earth. There is a theory that all the continents were once all one big piece of land named Pangaea‚ and over millions and millions of years the land of Pangaea started to split apart into many different continents. It divided Panthalassa‚ the large global ocean that

As seen in table 4 we can see that the fault is a reverse fault because the plates are exact opposite of each other the are flipped opposite of each other. The north side is moving up while the south side is moving down. An observation made at the fault was that the sediments were weathered and partially covered in mold meaning

Tsunamis‚ the ins and outs What is a tsunami? Tsunamis (Japanese for “Harbor Wave”) are series of waves that are characterized by their massive wavelengths‚ often about 120 miles long‚ whereas a normal wave has one of about 333 feet‚ and destruction that they bring when they hit land. They are often called tidal waves‚ but incorrectly so. They have virtually nothing to do with the tides. Tsunamis can range from a few feet in height to over a hundred feet

1. Explain the difference between a “reserve” and a “resource”. What factors influence estimates of reserves and resources for commodities such as minerals or fossil fuels? Resources and reserves are similar in that the both benefit humanity. Resources are materials that can be used to satisfy human needs‚ or used as support. Reserves on the other hand are known deposits with the ability to extract the available material economically; the size of these reserves is not always known or defined

very long time. The last eruption was in 8051 BC. Mount Garibaldi began erupting about 250‚000 years ago and has grown steadily since then. Like most of the Cascade volcanoes‚ it has its own origins in the Cascadia subduction zone; a long convergent plate boundary that stretches from mid- Vancouver Island to Northern California. The first European to see the mountain in 1792‚ Captain George Vancouver‚ traded with the local natives in the area. When skiing became popular in the 1940s‚ Vancouver skiers

Andes: 500 km Countries the Andes Covers: Argentina‚ Bolivia‚ Chile‚ Colombia‚ Ecuador‚ Peru‚ and Venezuela How were the Andes formed? The Andes were formed due to the compression‚ the act of tending to come together from different direction of plate boundary‚ just off the western coast of the continent of South America. The oceanic crust is being forced against the continental crust which forms the continent of South America. The collision causes it to build up which causes deformation (changing

US. Earthquakes California lies on a conservative plate boundary where the Pacific plate and the North American plate are the components. There are separated by a transform fault‚ known as the San Andreas Fault. The Pacific plate is moving north comparative to the North American plate however the fault is not smooth and so friction between the plates occur causing plates to lock. The continued pressure created by the movement of the plates around these locked portions of the fault causes the crust

off the North East Coast of Japans main island Honshu. Why? Japan is located on the eastern edge of the Eurasian Plate. The Pacific Plate‚ which is an oceanic plate‚ subducts the Eurasian plate‚ which is a continental plate‚ to the east of Japan. This type of plate margin is known as a destructive plate margin. The process of subduction is not smooth. Friction causes the Pacific Plate to stick. Pressure builds and is released as an earthquake. So what? The earthquake occurred at a relatively shallow

| | | | This vowel is known as the long a sound and it has the same sound as the alphabet letter A. Try to practice simple words such as: late‚ eight‚ and hate. Remember that you have to open your mouth wide for this sound.The long a sound is written as eɪ in IPA. Therefore‚ you can think about pronouncing the long a sound as the short e sound plus the short i sound. Many non native English speakers pronounce the long a sound as the short e sound because they drop the short i sound. |
