Hardness refers to the strength of the forces holding atoms together in a solid mineral. The Mohs scale will tell how easily a mineral can be scratched. It has a range from 1 to 10. Diamonds are a 10 on the Mohs scale. They are the hardest minerals in the world. The color of a mineral is often easy to identify. Many minerals are found in a range of colors. This is true for diamonds also. They can be yellow, brown, blue, green, orange, purple, black, pink, red, or colorless. Colored diamonds have impurities that cause them to change colors. Colorless diamonds, however, are very pure. Luster refers to how a mineral looks when it reflects light. A minerals luster could be metallic, dull, pearly, or adamantine. Diamonds have adamantine luster–their brilliant sparkle. Streak refers to the color of the powder left by a mineral. Streak is often found after a mineral is scratched on a porcelain tile. The color of the streak left on the tile helps to identify the mineral. The streak of a diamond is white.

What season is the Southern Hemisphere experiencing when the Northern Hemisphere is experiencing summer? Explain your answer.
The Southern Hemisphere experiences Winter during Northern Hemisphere's Summer. The reason why, is because the earth's axis is causing the North Pole to lean towards the sun.
It's the opposite in NH Winter and SH Summer. The South Pole is leaning towards the sun at this time.

Name and describe three measures of central tendency used to summarize data.
Read the assignment carefully and make sure you answer each part of the question or questions.
After you've written your response, go back and read it again to make sure your thoughts are clear.
Answer:
Explanation:
You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.
There are three main measures of central tendency: the mode(the number that occurs most often) the median ( the middle value in the list of numbers) and the mean (the average number in the list of numbers).
Answer:
The mean, median, and mode are three of the most commonly used measures of central tendency.
Explanation:
Quantitative variables are often summarized using numbers to communicate their central tendency. The numerical average; calculated as the sum of all of the data values divided by the number of values.
Describe the 3 layers of the mantle
Answer:
The 3 main layers are the core, mantle and crust
Explanation:
Answer:
I hope this is the answer for your question
Explanation:
Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.
The mantle is located directly under the Sima. The mantle consists of very hot and dense rock. This layer of rock flows like asphalt under heavy weight. This flow is because of the greatest temperature differences from the bottom to the top of the mantle. The reason behind the plates of the Earth move is the movement of the mantle. Its temperature varies between 1600 oF at the upper part to 4000 oF near the bottom.
Explain the difference between accuracy and precision.
Answer:
accracy describes the diffrence between the measurement and the part's actual value , while precision describes the variation you see when you the same part repeatidly with the same device!

This image shows an overhead view of Atlanta’s buildings, structures, and surrounding areas and a heat map of the area. What is the most likely reason for the high temperature in the regions indicated in dark red? two maps of Atlanta, one showing an overhead view of Atlanta's buildings and structures and other showing the heat levels in the area Atlanta’s roads and buildings absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. Atlanta’s trees and forests absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. The rural areas around Atlanta absorb more heat than the urban areas, causing an overall increase in the city’s temperatures.

Why do you use immersion oil with a 100X objective lens?
Answer:
For example, by placing a substance such as immersion oil with a refractive index that is equal to the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed
Explanation:
Hope you have a great day :)
The 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens)
What is Immersion oil?Oil immersion is a technique used to increase the resolving power of a microscope by immersing both the objective lens and the specimen in a transparent oil of high refractive index, resulting in an increase in the numerical aperture of the objective lens.
An immersion oil used in microscopy essentially consists of a solution of hydrogenated terphenyl, a polybutene, and a mineral oil, which provides a solution with a refractive index between 1.5100 and 1.5240.
It is used for the highest power objectives because light refraction from low power magnification microscope objective lenses such as (10X and 40X) is negligible and not noticeable.
Thus, the 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens).

Which of the following best describes the relationship between frequency and wavelength of electromagnetic waves?
A. If the frequency remains constant, the wavelength size increases.
B. As the wavelength size decreases, the frequency decreases.
C. As the frequency increases, the wavelength size decreases.
D. If the wavelength remains constant, the frequency increases.
Answer:
b makes the most sense
Explanation:
Answer:
I think C is the correct answer.
Explanation:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
