Mercury the closest planet to the Sun: Mercury‚ and the other inner planets‚ condense from the heavier elementes. Condensing closest of all to the sun‚ Mercury is rock solid. Outwardly‚ Mercury is like our Moon: rocky‚ cratered‚ barren. But inside‚ like Earth‚ is an iron-rich core. That core is as big as the Moon and‚ at 70% iron‚ Mercury is the densest planet of all. Also Mercury’s day is twice as long as its year. The day lasts 176 Earth days‚ the year just 88. But it gets stranger... If you

Plate Tectonic Assignment 1. The Juan de Fuca and Cocos plates were once part of a much larger plate called the _________ plate. 2. How long ago was this plate the dominate plate? 3. What plate(s) are the remnants of this former plate? 4. What kind of plate boundary exists between the Juan de Fuca and the North American plate? 5. What kind of plate boundary exists between the Pacific plate and the North American plate? 6. What tectonic process is ongoing between Baja California and the North

also made up of iron and nickel. It is still extremely hot‚ with temperatures similar to the inner core. 3. The mantle is the widest section of the Earth. It has a thickness of approximately 2‚900 km. The mantle is made up of semi-molten rock called magma. In the upper parts of the mantle the rock is hard‚ but lower down the rock is soft and beginning to melt. 4. The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live

they react and form carbon dioxide. They become “uncomfortable” like it is allergic to each other and it automatically breaks apart into water and carbon dioxide‚ which makes the liquid inside comes out. Answer to question 3: Volcanoes form when magma from within the Earth’s upper mantle works its way to the surface. Over time‚ the volcano continues to erupt and it gets bigger and bigger. We also collected the data and got these results: Our hypothesis was half correct. The hotter the vinegar

Who is the scientist who did much of the early work on continental drift? In the early 20th century‚ German scientist Alfred Wegener published a book explaining his theory that the continental landmasses‚ far from being immovable‚ were drifting across the Earth. What evidence did this scientist have to support his idea of continental drift? Wegener noticed that the continents seemed to fit together‚ not at the continuously changing shoreline‚ but at the edge to their continental shelves

of Nea Kamini. It was created in 1570 and over time has developed rudimentary soil. The second point was on the south rim of the great Daphni crater. The crater is made up of scoriaceous lava. This is spongey lava that is filled with gaps from magma gas bubbles. We also viewed the Fouque and Reck lava domes that were formed from the eruption of 1939-1940. The third point was the central twin crater of Nea Kameni and was formed in 1940 by 2 hydrothermal eruptions. The east rim of the crater had

Plate Tectonics Chart Amanda Wright GLG 150 February 24‚ 2013 Karen Hansen Plate Tectonics Chart 1) How does the motion of the tectonic plates affect the climate? Climate can be affected by many things. One of the biggest affects may be the motion of the tectonic plates. The Earths plates have been in motion approximately since its beginnings or shortly after‚ continuously causing climate to change. The Earth’s movement of plates as well as the apparent polar wandering can both play a role

This is because of a huge underwater volcano. It was caused by volcanic magma erupting from the sea floor in the construction plate‚ the Mid-Atlantic Ridge. Iceland has the greatest concentrations of volcanoes in the world. It has 130 volcanic mountains. Some of them are greater and more famous than the others. Most of them

Continental Drift‚ why True? Continental drift is the process of large mass of land and rocks unceasingly moving for a long period of time‚ which can be explained by what is called "Plate Tectonics". Due to the fact that continental drift is a theory‚ there is evidence and other sets of statements to back it up. According to Wegener‚ a geologist stated that segments of the Earth has made continental drift true (possible) whilst other pieces of information supported that continental drift has happened
