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 a large number of fumaroles-hot gas vents that release a combination

high heat and pressure. Magma erupts from beneath the surface and cause lakebeds‚ mountain peaks and huge boulders. Crater Lake in Southern Oregon at 4‚000 feet is the deepest lake in the nation‚ and was formed when Mount Mazama self-destructed 7‚700 years ago. In the center of the beautiful clear lake is Wizard Island‚ a cone of cinders formed by a later eruption in the crater. Mount St. Helens in southern Washington erupted dramatically in 1980‚ causing the collapse of its entire northern face

Even though the rest of the solar system objects may seem like tiny dots from Earth‚ our celestial neighbors are still important to learn about. The importance of this task has led many experts here at Wikijunior to donate their time and talents to bring this volume together. Wikibooks is a project of the Wikimedia

Mars has so many impact craters on its surface‚ the largest of which is the Borealis basin. This crater is so huge‚ it measures about 5‚300 miles from end to end covering 40% of the face of Mars. Scientists believe that this could be the result of a gigantic impact that happened when the solar system is still being

Creation of Oahu by Volcanism Karen Ta: 430 BOT 450 TR 10:30-11:20 Volcanoes are magnificent formations from an opening in a planet’s crust. They form when magma‚ volcanic ash‚ and gases escape from a magma chamber below the surface of the planet. Tectonic plates cover the surface of the planet and are constantly moving. Volcanoes are generally found where these plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning

REPORT Introduction I am doing a project that involves the ‘works’ of Gravity - discovered by Sir Isaac Newton. Gravity: the force that attracts a body toward the centre of the earth‚ or toward any other physical body having mass. For most purposes Newton’s laws of gravity apply‚ with minor modifications to take the general theory of relativity into account. My experiment is labeled The Marble Dropping experiment and has been done in many different ways using different methods and equipment.

Journey to the Center of the Earth is an 1864 science fiction novel by Jules Verne (published in the original French as Voyage au centre de la Terre). The story involves a professor who leads his nephew and hired guide down a volcano in Iceland to the "center of the Earth". They encounter many adventures‚ including prehistoric animals and natural hazards‚ eventually coming to the surface again in southern Italy. From a scientific point of view‚ this story has not aged quite as well as other Verne

Also the first thing he mentions when he first gets to the Craters house is the car. Another action that makes him grotesque is that he was at The Hot Spot with Lucynell‚ went for a drive and never came back for her. This makes him grotesque because he left a mentally challenged girl by

evening star. Early astronomers also referred to Venus as Earth ’s sister planet. Both are considered young planets due to the low number of craters and both are similar in size‚ and their chemical compositions are similar. The surface of Venus has many features‚ which are similar to the Earth such as canyons‚ volcanoes‚ lava flows‚ rift valleys‚ mountains‚ craters‚ and plains. The comparisons basically end there. Venus differs from the Earth in many ways. The one big difference that I noticed was the
