Igneous Rocks Igneous rocks originate from deep within the Earth’s crust. Igneous rocks (from the Greek word for fire) are formed when magma crystallizes and solidifies. An increase in temperature‚ a change in the composition‚ or decrease in the pressure can cause melting of these rocks in the mantle which form igneous rocks. The melt begins deep below the surface of the Earth close to active plate boundaries. As the temperate increases the rocks rise toward the surface. Igneous rocks are divided

their fair share of uses. One of the most interesting theories that cannot be observed is the Moon’s magnetic field‚ and why there is not one anymore. Moon rocks Colwell 7 brought back from the Apollo age astronauts shows that at some point the moon did have a magnetic field as strong as the Earth’s at some point. From analyzing the way the rock formed‚ the scientists can determine how long the Moon had a magnetic field. From their research they have discovered that a magnetic field persisted for much

The Big Rocks of Life! One day a wise teacher was speaking to a group of his students. He pulled out a one-gallon‚ wide-mouthed mason jar and set it on a table in front of him. Then he produced about a dozen fist-sized rocks and carefully placed them‚ one at a time‚ into the jar. When the jar was filled to the top and no more rocks would fit inside‚ he asked‚ "Is this jar full?" Everyone in the class said‚ "Yes." "Really?" he asked. "Let’s see." He reached under the table and pulled

explain how rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks. Operation of the rock cycle The Rock Cycle

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

One of the positive traits of the Aztecs is their cultivation of a very refined‚ sensitive‚ and morally base culture. 31. The Aztecs and the Greeks were compared in that they both combined the body (materialism) and soul (spirituality). 32.

DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common‚ B form‚ is the structure most people have heard of. It consists of the right

Metamorphic rocks are originated within the earths crust. Metamorphic rocks are created when both pressure and heat meet at the right time. During metamorphosis the rocks do not melt the heat and pressure just change the make-up of the rock. There are two types of metamorphosis low grade and high grade. Low grade metamorphosis occurs at 400 degrees C and 400MPa‚ while high grade is anything above 400 degrees c and 400MPa. Once the temperature reaches a little over 600 degrees Celsius and over 600MPa
