Crust

The crust is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle. The crust of the Earth is very thin compared to all of the other layers, measuring only three to five miles deep under oceanic crust. The temperature of the crust can vary from air temperature to 1600 degrees Fahrenheit. One example of how the crust relies on the other layers because the seven continents and ocean plates practically float across the mantle which

are moving away from each other and new crust is being made, then ask the question: Why is the earth not getting larger? Poll some of the answers from the learners and begin the session. Convergent Boundary:(20 minutes) Explain to the class that another type of plate tectonics, when the plates crash into each other, is called convergent, and that this causes the Earths crust to be pushed into the interior where it is remelted at the same rate the new crust is being made. Discuss the two kinds of

How and when did the Earth produce its core, mantle and continental crust? It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core

meteor or an asteroid hits the surface and it explodes leaving a crater or dent on the planet's crust. Over the years, craters tend to lose its shape. You can tell if it is a crater or not. After a asteroid or meteor hits the surface and explodes, it leaves dust particles of what the asteroid or meteor is made up of. Take a sample and test the dust to see if it was an asteroid, meteor, or just a dent in the crust. The largest crater on mars is the Schiaparelli. Mars has the largest existing volcano named

The Crust is solid silicate rock. It's mostly made of basalt. The motion of the lithospheric plates give rise to earthquakes and volcanism on the surface of the Crust.” “Wow you really know a lot about the Crust” said Dr. Phil. “I sure do” said Crusty.”Where are you going next?” asked crusty. “To the Mantle” said Dr. Phil. “Oh you'll meet monica the dragon

The crust, mantle, and core of the earth are all very fascinating. Also, a theory called plate tectonics attempts to explain many phenomena that occur on the surface of the earth, such as earthquakes. Some properties of the earth's surface are its layers, the plate tectonics theory, and earthquakes. The layers of the earth are very complex. These layers are the crust, mantle, and core (Wile 132). The core is divided into two regions: the inner core and the outer core (Wile 131). Earth's crust is

During the Scottish Enlightenment, a period of increased intellectual activity in the 18th and early 19th century, individuals tended to explore multiple disciplines of study (Young). One prominent Scottish Enlightenment figure was James Hutton (1726-1797), who worked as a lawyer, geologist, chemist, physician, farmer, and naturalist during his lifetime. Hutton, along with other significant Enlightenment figures, Joseph Black and Adam Smith, founded the Oyster Club. This intellectual club was based

There are tons of natural phenomenon. Such things as landslides, earthquakes, volcanoes, meteors, and floods. Today in this article the two topics of Meteors and floods will be the main focus. These disasters can change the earth an astronomical amount. For meteors such things as their craters and their effects on the climate. Floods are more of a tricky subject, but their main effects on the Earth are the effects of erosion and the aftermath of environmental consequences. Moreover, on this

The canadian shield is made up of bedrock that existed from an ancient continent called Actica that last existed about 2.5 billion years ago.This continent also formed into scotland, greenland, and siberia. The area was originally full of mountains before it was lowered down to what we know as the canadian shield This was likely caused by water erosion that sank the land around it, leaving the bedrock exposed, resulting in the forms that are now known as the canadian shield.The Canadian Shield is

Early predictions have thrown up some rather strange and peculiar thoughts as to what is making up our Earth, but now day¡¦s scientists can be confident that the Earth is made up of what they think. As from experiments and other sources of information a picture to what is really
