about how tectonic activity and how it comes to form Iceland. Location Iceland is an island between the Greenland Sea and the Northern Atlantic Ocean‚ northwest of the United Kingdom Iceland is situated right in the North Atlantic Ocean. Iceland‚ positioned on the Mid-Atlantic Ridge (A mid-ocean ridge is an underwater mountain range that is formed by plate tectonics) makes it vulnerable to volcanic eruptions and sometimes even earthquakes. The island is spilt by the North American plate and Eurasian

In the event that the development proceeds in light of current circumstances and course‚ in 10 million years‚ Los Angeles‚ presently at low scope‚ will have moved northward to the same scope as San Francisco. In 50 to 60 million years‚ Baja California and parts of California west of the San Andreas flaw will have turned out to be totally isolated from whatever is left of the North American Plate.

Did you know that one day in the past the continents were connected with each other? Continental drift states that the continents that we know today were once one large landmass called‚ Pangea. Many people argue with the theory about the continental drift‚ because no one yet has proven to the theory’s idea. Many people have been trying to find ways of how the continental drift could have happen‚ by researching objects from the past. This gave scientist or people another point of view about the continental

the earth’s tectonic forces are trying to create new plates by splitting old ones apart. A rift is defined as a fracture in the earth’s surface that widens over time. A more technical definition for a rift is an elongated basin bounded by opposed steeply dipping normal faults. Geologists continue to debate exactly how rifting occurs. They do believe the process is so well displayed in East Africa‚ having given the new plate to be a name. The name is the Nubian Plate. The Nubian Plate makes up most

Dead Sea Scroll The settlement of Qumran is one kilometer inland from the northwest shore of the Dead Sea. The scrolls were found in eleven caves nearby‚ between 125 meters (e.g.‚ Cave 4) and one kilometer (e.g.‚ Cave 1) away. None were found within the settlement‚ unless it originally encompassed the caves. In the winter of 1946–47‚ Palestinian Muhammed edh-Dhib and his cousin discovered the caves‚ and soon afterwards the scrolls. John C. Trever reconstructed the story of the scrolls from several

Convections Currents The main idea that I would like you to get from this set of notes is that convection currents are a swirling motion of a fluid that needs a heat source and a cold source to work. The rest of the notes will deal with supporting this idea and giving some examples of convections currents here on earth. Once the earth collects enough material it will start to get so heavy that it compresses inward toward the center of gravity a lot. This smashing of
