earthquakkkkkkkes and volcanoes

dear:ladies and Gentlemen
Earth Quakes
i want you to know about earthquakes because it is important because it destroy houses  and also  tectonic plate made the earth quake  because wine the earth brake and it will be fault line the earth quakes.i know that the earth quakes destroy and then often the damage the houses burning and also the people were building that are hall and strong and they are doing this for safety.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.






earthquake of you know the answer comment me!!!!

                                       1.what causes earthquake?:its the tectonic plates?:

                                     2.how to earthquakes change the surface of the earth?:

                                       3.describe the damage couched by earth quakes?:

                           4.why is it important for people to learn more about earthquakes?:

                                        5.where are earthquakes most likely to occur?

                                         6.how are tsunamis related to earthquakes?




volcanoesssssssssssss

volcano is a came thing that has magma inside it. Also the volcanoes are very dangerous.A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface. Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent.
A volcano is active if it is erupting lava, releasing gas or generates seismic activity. A volcano is dormant if it has not erupted for a long time but could erupt again in the future. Once a volcano has been dormant for more than 10 000 years, it is termed extinct.
The explosiveness of a volcanic eruption depends on how easily magma can flow and the amount of gas trapped within the magma. Large amounts of water and carbon dioxide are dissolved in magma causing it to behave in a similar way to gas expanding in fizzy drinks, which forms bubbles and escapes after opening.
As magma rises quickly through the Earth's crust, gas bubbles form and expand up to 1000 times their original size.
Volcanoes can be different in appearance with some featuring perfect cone shapes while others are deep depressions filled with water. The form of a volcano provides a clue to the type and size of its eruption which is controlled by the characteristics and composition of magma. The size, style and frequency of eruptions can differ greatly but all these elements correlated to the shape of a volcano.

Learning about braiiiiiiis and your nervous system

Ladies and Gentlemen,about brainsbrain is important because it helps you to move your body and also it helps you to be smarter.  Also the brain learns so many things so if you are listening the brain will give you all his answer same times your brain do same thing by it self like wine you throw same thing that is dangerous.  Also with out your brain you cant move, touch, feel. The brain is the command center of your entire body. The brain is the body's main information center. It is made of billions of neurons. The brain helps the body respond to the information it receives from the senses. The brain also processes thoughts. When you think, neurons in your brain are working.     The brain has three main parts. The largest is the cerebrum, which controls vision, touch, and other senses. It also handles movements you have control over. Thinking takes place in the cerebrum. The cerebellum is another section of the brain. The cerebellum helps control balance and coordination. Another part of the brain is called the brain stem. The brain stem is the link to the spinal cord and it also controls digestion, breathing, and heartbeat.
Nervous system


Nervous system is important because with out the nervous system you cant taste,fell,here or see.Also wine you eat a rice the nervous system sent to the brain that you are eating and then the brain tells you you are eating rice.Also the service system say to the brain that you want to cry so then wine the brain gets the massage from the nervous system and then the brain lets you to cry.Nervous System This information will help you find out why the nervous system is the control and communication system of the body.The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system.

Mixture

MIXTURE
Mixture is same thing that is sap orated between the chex-mix and a candy and they are different 
shape and the chex-mix are brown and the candy has deterrent  kind of color and also it is mixture.A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components. Some examples of mixtures are a tossed salad, salt water and a mixed bag of M&M's candy.
In Chemistry, a mixture is a material system made up of two or more difference       substances which are mixed but are not combined chemically. A mixture refers to the physical combination of two or more substances on which the identities are retained and are mixed in the form of solutions, suspensions, and colloids. mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A mixture refers to the physical combination of two or more substances on which the identities are retained and are mixed in the form of solutions, suspensions, and colloids.
Mixtures are the one product of a mechanical blending or mixing of chemical substances like elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup.[1] Despite that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by physical (mechanical or thermal) means.Azeotropes are one kind of mixture that usually pose considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes or, even a blend of them).
