Rogue Waves!!

Rogue Waves which are also known as freak wavesmonster waveskiller wavesextreme waves, and abnormal waves,are relatively large and spontaneous ocean surface waves that occur far out in sea, and are a threat even to large ships and ocean liners.  In oceanography, they are more precisely defined as waves whose height is more than twice the significant wave height (SWH).  Rogue waves are not tsunamis, which are set in motion by earthquakes [and] travel at high speed, building up as they approach the shore. Rogue waves seem to occur in deep water or where a number of physical factors such as strong winds and fast currents converge. This may have a focusing effect, which can cause a number of waves to join together.

Soil!


      Ultisol

Georgia soils typically are lacking of nutrients, but support a variety of southern pine trees. Red clay soils in Georgia are not well aerated and must often be supplemented with manure and soil conditioners in order to support landscape features throughout Georgia's suburban areas.
One of the ways we identify soil is by looking at the soil and we also use the Munsell soil color chart to identify.

Extremophiles

An Extremophile is an organism that thrives in and may even require physically or geochemically extreme conditions that are detrimental to most life on Earth.  Most known extremophiles are microbes.  There are many different classes of extremophiles that range all around the globe, each corresponding to the way its environmental niche differs.  Many extremophiles fall under multiple categories.  
Thermophiles- thrive under extremely high temperatures
Acidophiles-thrive under extreme acidic conditions
Halophiles-thrive in environments with very high concentrations of salt

Psycrophiles

Psycrophiles are the type of extremophiles that just love low temperatures. 
 They do not like temperatures above 12°C for reproduction.
This is one environment that Psycrophiles dwell.  


GEOLOGY!

Igneous Rock
Igneous Rock is formed through the cooling and solidification of magma or lava. It may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. 
Basalt 
Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet.  Basalt has also formed on Earth's MoonMars,and Venus.  Basalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones and in making statues
Granite
Granite is a common and widely occurring type of intrusivefelsicigneous rock and usually has a medium- to a coarse-grained texture.  Granites can be pink to gray in color, depending on their chemistry and mineralogy. Granite is nearly always massive, hard and tough, and therefore it has gained widespread use as a construction stone.  Granite is formed form magna and it is the most abundant basement rock.  


Metamorphic Rock
Metamorphic rock is the transformation of an existing rock type in a process called metamorphism, which means "change in form".
It makes up a large part of the Earth's crust and may be formed simply by being deep beneath the Earth's surface.  It is subjected to high temperatures and the great pressure of the rock layers above it. The study of metamorphic rocks provides us with information about the temperatures and pressures that occur at great depths within the Earth's crust.

Slate
Slate is a fine-grained, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash.  When cut expertly, many slates will form smooth flat sheets of stone which have long been used for roofing and floor tiles and other purposes. Slate is frequently found grey in color, especially when seen in covering roofs, however, slate occurs in a variety of colors.  

Quartzite
Quartzite is a hard metamorphic rock which was originally sandstone. Sandstone is converted into quartzite through heating and pressure. Quartzite is a decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stair steps.  It is very resistant to chemical weathering and often forms ridges and resistant hilltops.  Pure quartzite is usually white to grey, though quartzites often occurs in various shades of pink and red due to varying amounts of iron oxide. Other colors, such as yellow and orange, are due to other mineral impurities.

Sedimentary
Sedimentary rock is formed by sedimentation of material at the Earth's surface and within bodies of water.  Sedimentation is the collective name for processes that cause mineral and/or organic particles.  Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by waterwindmass movement or glaciers.  The sedimentary rock cover of the continents of the Earth's crust is extensive, but the total contribution of sedimentary rocks is estimated to be only 5% of the total volume of the crust.  

Sandstone  

Sandstone is composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust.  Sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray and pink, white.  Fine-grained aquifers, such as sandstones, are more apt to filter out pollutants from the surface than are rocks with cracks and crevices.    

Limestone
Most grains in limestone are skeletal fragments of marine organisms such as coral.  Limestone makes up about 10% of the total volume of all sedimentary rocks.  Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces.     





WHERE iS MY BABY?!?!?!

This is my unborn baby Greg...
I planted him about three weeks ago and he still has yet to sprout!!!!!!:(:(
I water him everyday and keep him in my window sill in the sunlight by my bed...I really don't know what went wrong :(
