and events that at one point affected both the Moon and Earth can now only be found on Earth. The Earth and Moon are formed with the same materials‚ just with different amounts. The Moon contains no life in any shape or form. We also discovered a magma ocean on the Moon and other geographical features and their formations. 837.87 pounds of of lunar rocks were brought back to Earth. The rocks range from 3.2 billion years all the way two 4.6 billion years. Even though NASA had plans of continuing

is finding the best hydrothermal place. As we know‚ if we want to find big resources of water‚ wind‚ sun‚ etc. we need to go to the areas were normally we can find the resource. In this case‚ geothermal power is primarily available where the hot magma finds its way close to the surface and heats ground water. But this geothermal spots don’t occur everywhere‚ they are located‚ for example‚ in USA in Western States‚ Alaska‚ and Hawaii. The big key to universal use of geothermal resources

volcanic cones: Kibo (5895 metres)‚ Mawenzi (5149 metres) & Shira (3962 metres). Volcanic conditions Although it’s dormant‚ Kilimanjaro has fumarole (an opening in the earths crust) that emits gasses in the crater on the main summit of Kibo. Molten magma is just 400 metres below the summit crater. A number of landslides have occurred in the past creating an area called the Western Breech. The last known eruption was approximately 360 000 years ago‚ but the most recent volcanic activity took place approximately

The Naica mines are naturally occurring caves‚ located in Chihuahua‚ Mexico. The Naica mines are working mines rich in lead‚ zinc‚ and silver‚ which are owned by Mexico’s largest lead producer‚ Industrias Penoles. Within the Naica mines are caves filled with giant selenite crystals‚ discovered by miner brothers‚ Juan and Pedro Sanchez in 2000. The caves were discovered while drilling through the Naica fault during a mining expedition. The giant crystal caves are in the shape of a horseshoe and have

Describe contact metamorphism. Cold rock is intruded by hot magma 13. Describe regional metamorphism. Motions of plates at convergent plate boundaries 14. How is metamorphism like cooking (called an "isochemical" process). As temp and pressure increase‚ atoms become immobile‚ therefore creating new minerals

The Earth is constantly moving. The earth is not stable because‚ the plates are all ways moving.There is different boundaries for the plates in the earth there is convergent‚ Divergent‚ and transform boundaries. The transform boundaries rub together and causes enough friction that when the potential energy lets loose it creates an earthquake. convergent boundaries we’ll come together that can help make mountains because when one plate is more dense than the other plate‚ the more dense plate will

Welcome to the Galapagos Islands! The Galapagos are an archipelago of several volcanic islands located in the Pacific Ocean. The archipelago consists of 13 major islands‚ six minor islands‚ and 40 smaller rock formations and reefs spread out over 17‚000 square miles of ocean. They are born to create fire‚ and in the last 200 years a remarkable 50 plus eruptions have occurred. Looking into the geographic location and plate tectonic settings can easily help show why more than 50 eruptions have occurred

research and evidence for this to become a leading theory. This means that although volcanic and seismic events help to prove the plate tectonics theory valid‚ there is also a range of other factors involved. Vulcanicity is the surface presence of Magma within the Earth’s crust. Whereas seismicity is where the

tectonic plates meet; the heavier plate slides underneath the light plate and melts down to become magma. This mixes with trapped gases and steam in the magma chamber (Gates‚ 2009). Pressure from surrounding rocks forces the magma to the surface through weak points‚ such as fractures and when it reaches the crust an explosion occurs with regard to the amount of pressure available and the viscosity of magma creating a subduction volcano. Volcanoes can additionally be formed when two tectonic plates move
