Assignment Summary For this assignment, you will make a scale model—a “core sample”—showing the layers of the Earth: crust, lithosphere, asthenosphere, mantle, outer core, and inner core. Background Information The Earth is composed of six layers with differing thicknesses and properties. The crust forms both land and seafloor. It is thickest under mountains and thinnest under ocean beds. The crust’s thickness ranges from 5 to 70 km thick. The lithosphere consists of the crust plus the upper mantle. It is solid and is about 100 km thick. The asthenosphere is a semisolid layer under the lithosphere. It is about 180 km thick. The lower mantle is 2,250 km thick and is solid, but very hot, rock. The outer core is molten rock and it is 2,266 km thick. Finally, the inner core is 1,210 km thick, and it is solid iron and nickel. Remember that as you go deeper into Earth’s layers, temperature and pressure increase. A core sample is made by drilling into the Earth and pulling out a long cylinder of rock. Geologists analyze these core samples to learn more about Earth’s history and composition. So far, geologists have not yet succeeded in drilling into Earth’s mantle. You will construct a scale model of a core sample. When something is “to scale,” it has a uniform reduction or enlargement. You will calculate how deep each layer should be in centimeters, based on the actual depth of Earth’s layers in kilometers. The percentage of the total for each layer remains the same, but the actual number of units changes. Step 5: Create a typewritten paper describing your model of Earth’s layers. a) Type several paragraphs describing your “core sample” of Earth’s layers in detail. i. Explain what a core sample is. Then, tell whether it is currently possible to take a core sample like the model you’ve created. ii. Compare and contrast the layers in your model, including the significance of the colors. iii. Discuss what it means to create a scale model. iv. Include a table with the values you determined for each layer. v. Discuss the relationships of each layer to the others, including depth. b) Answer the following question in a separate paragraph. i. How does your “core sample” model of Earth’s layers differ from the actual layers of the Earth? c) Make sure your paragraphs include correct sentence structure, punctuation, grammar, and spelling. d) Ask your teacher where you should save your work. Your teacher may also have specific guidelines about the file name you should use.

yo I hope this gets you a good grade. I have the same thing due on Nov. 9. did it the same day it was due. good luck. you will need to make the thing yourself.

Explanation:

A core sample is a cylindrical section of a natural substance. Most core samples are made by drilling with special drills into the substance, such as sediments or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". It is currently not possible to take a core sample like this one.

The difference in these layers is that the farther down you go the hotter and more dense it gets. You need to make the layers different colors so you know which layer is which and, how deep the layer goes.

What it means to make a scale model is to make a model of something and make it a certain amount smaller than the original.(the entire model should be the same amount smaller than the original.)

Starting at the center, Earth has four different layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. The inner core is a solid metal ball and is extremely dense, it’s made mostly of iron and nickel.the outer core is also made from iron and nickel, just in liquid form. The mantle is Earth’s thickest layer and is made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (like caramel candy).Earth’s crust is like the shell of a hard-boiled egg. It is extremely thin and cold. The crust is made of relatively light elements, especially silica, aluminum and oxygen.

How does this “core sample” model of Earth’s layers differ from the actual layers of the Earth? Well, this model is much smaller and is Impossible  to do in real life. Example, the metal used for making the hollow rods to take these core samples would melt when they get to the mantle much less the inner core.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.

it is the most commonly accepted one
