While soil minerals and organic matter hold and store nutrients, soil water is what readily provides nutrients for plant uptake. Soil air, too, plays an integral role since many of the microorganisms that live in the soil need air to undergo the biological processes that release additional nutrients into the soil.]]> 2016-10-25 01:50:05 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132887196 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132887386 A mountain range is a series or chain of mountains that are close together. The world's tallest mountain ranges form when pieces of Earth's crust—called plates—smash against each other, in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision.]]> 2016-10-25 01:51:48 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132887386 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132887922 Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. ]]> 2016-10-25 01:57:49 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132887922 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888679 A volcanic eruption is one of the most dangerous and magnificent natural disasters.  When a volcano erupts, the volcano sends out ash clouds, lava and even volcanic bombs.  There is a high risk of danger from slow moving lava; though, the lava might move slowly, it is very dangerous and can cause a lot of damage to property and human life.]]> 2016-10-25 02:05:33 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888679 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888801 A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. Even a small geyser is an amazing phenomenon; however some geysers have eruptions that blast thousands of gallons of boiling hot water up to a few hundred feet in the air. Old Faithful is the world's best known geyser.]]> 2016-10-25 02:06:53 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888801 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888947
Landslides are a serious geologic hazard common to almost every State in the United States. It is estimated that in the United States they cause in excess of $1 billion in damages and from about 25 to 50 deaths each year. Globally, landslides cause billions of dollars in damages and thousands of deaths and injuries each year (Schuster, 1996; Kirshbaum and others, 2009).]]> 2016-10-25 02:08:37 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132888947 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132889208 The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.]]> 2016-10-25 02:11:35 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132889208 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132889466 The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material.

The role of water in the uppermost mantle has been explored to 6 GPa (~190 km) by a novel experimental approach in which the silicate melting solidus, the stability of hydrous phases and the water contents in nominally hydrous minerals (NAMs) were determined in each experiment. By varying water contents, including ‘dry’ and from ~500 ppm to 14.5 wt % H2O, i.e. from water in nominally anhydrous minerals (NAMs) to vapour-leaching conditions, we were able to clarify melting and vapour-leaching regimes. We determined the solidus and melting behaviour, and pargasite stability in model fertile lherzolite (MORB source) between 1.5 and 6 GPa. ]]> 2016-10-25 12:58:38 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132978890 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132982061 2016-10-25 13:06:51 UTC https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132982061 carrahamm1998 https://padlet.com/carrahamm1998/ja16uhyijdjs/wish/132982219 The living things in an ecosystem are called biotic factors.

These include the fossil fuels, oil, natural gas, and coal and nuclear energy. Today, close to 84% of the total amount of energy used globally comes from fossil fuels.are those which can be replenished over time by some natural process, including farming. These resources have the ability to be renewed over a short period of time.
