Why is Mars red or matter afact why do we need to know about mars. Mars is red because in the acticle www.spaceanswers.com states that “iron rusting rocks and soil on the surface of mars contained a dust composed mostly of iron and small amounts of other elements such as chlorine and sulfur. The rocks and soil were eroded by wind and the dust was blown across the surface by ancient volcanoes.” Mars is really weird because the iron oxide forms a rust dust that floats in the atmosphere and sits as

Introduction The Permian was the last period during the Paleozoic era. It occurred approximately 299 million years ago and was the point in time in which much of the earth’s land mass came together to form the supercontinent‚ Pangea. While years of study has relieved the climate conditions and life forms present during this period‚ the events surrounding the mass extinction that signified its end remains a mystery today. The end-Permian mass extinction is regarded as the largest mass extinction

The ball mill is the key equipment for grinding after the crushing process‚ which is widely used in the manufacture industries‚ such as cement‚ silicate‚ new building material‚ refractory material‚ fertilizer‚ ferrous metal‚ nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. 1.The dry stone ball used by the diameter of the ball mill efficiency is the impact factor‚ ball stone ball diameter of ball mill size varies

GORGE- 1. A deep narrow passage with steep rocky sides; a ravine. 2. A narrow entrance into the outwork of a fortification. v shaped - River valley with a V-shaped cross-section. Such valleys are usually found near the source of a river‚ where the steeper gradient means that there is a great deal of corrasion (grinding away by rock particles) along the stream bed‚ and erosion cuts downwards more than it does sideways. However‚ a V-shaped valley may also be formed in the lower

up at the night sky you can see the moon has “darker and lighter patches” all over the surface (Duncan 89). Many generations used to think the dark spots were oceans. Those dark spots are called “maria” (Duncan 89). These spots are smooth‚ made of basalt from lava (Duncan 89). Billions of years ago when the meteor hit the moon‚ it “exposed molten rock beneath the crust”. Then lava would have flowed out‚ making the craters we see today (Duncan 89). Interesting fact: one of the most famous of the Maria’s

If it is hard stone‚ like granite or basalt material with high silicon. We can use jaw crusher、 cone crusher、 impact crusher（or sand making machine） and vibrating screen in production line. The secondary stage we choose cone crusher have following considerations: First‚ material hardness is

Igneous rock forms when the erupted lava reaches to the surface of the Earth through the cracks of the Earth. The lava cools very quickly and the rocks formed this way are made with small crystals. These rocks are known as the Extrusive Igneous rocks. Basalt is an example of this kind of Igneous rock. Obsidian is another kind of extrusive Igneous rocks which gets cooled so fast that it has no crystals and looks like black and shiny glass. Common features of the Igneous rocks: • The Igneous

The Stromboli stratovolcano off the coast of Sicily has erupted continuously for thousands of years‚ giving rise to the termstrombolian eruption. Lava composition Another way of classifying volcanoes is by the composition of material erupted (lava)‚ since this affects the shape of the volcano. Lava can be broadly classified into 4 different
