The color of the powder obtained when the mineral is scratched against a ceramic plate is streak.
What do you mean by mineral?
A mineral or mineral species is a solid chemical substance with a very well-defined chemical composition and a specific crystal structure that occurs naturally in pure form in geology and mineralogy.
Compounds found only in living organisms are typically excluded from the geological definition of mineral. However, some minerals (such as calcite) are frequently biogenic or are organic substances in the sense of chemistry (such as mellite). Furthermore, living organisms frequently generate inorganic minerals (such as hydroxylapatite) that are also found in rocks.

How does the ozone layer that protects us from harmful UV radiation today connect back to Threshold 5 of Christian's "Big History" - the emergence of living organisms? Choose 1 answer. B These first organisms were the ancestors of plants and animals that produce ozone through photosynthesis. The first bacteria converted glucose into nitrogen which makes up the ozone layer today. Asteroids that hit the earth during this time generated a layer of dust and compounds that make up the ozone layer. Some of the first single-cell bacteria emitted oxygen into the air, helping form the ozone layer.
what is the equivalent ratios and there are three options to choose from 7:6.
The equivalent ratios of 7:6 is: A. 14:12.
What are equivalent ratio?Equivalent ratios can be defined as the ratios in which when compare and contrast to one another we have the same or equal result.
In order to find or determine the equivalent ratio of 7:6 we would have to multiply each term of the given ratio which is 7:6 by 2.
Now let find the equivalent ratios of 7:6 by multiplying each term by 2.
Hence,
Equivalent ratios:
Equivalent ratios = (7: 6) ×2
Equivalent ratios=14:12
(7×2=14) (6×2=12)

which Points of the compass Concides with 0°, 180°, 225², 315°?
0° coincides with North, 180° coincides with south, 225° coincides with South west, and 315° coincides with North west in compass.
What is a compass?An instrument that shows the cardinal directions is a compass, which is used for geographic orientation and navigation. It typically consists of a magnetized needle or other component that may pivot to line up with magnetic north, like a compass card or compass rose.The use of a compass significantly increased travel's efficiency and safety, particularly while traveling by sea.The direction you desire to go from one location to another in regard to magnetic north is known as a bearing and is one of a compass's 360 points. On a map or immediately in the field, you can measure the bearing.Early Chinese scientists, maybe from the 11th or 12th century, may have invented navigational compasses. At the end of the 12th century, Western Europeans quickly followed.Compasses were probably first used as a backup when it was impossible to view the sun, stars, or other landmarks.Learn more about compass here:

define the word difusion
Answer:The definition of difusion is the spreading of something more widely.
Explanation:
Answer:
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient. Diffusion will continue until this gradient has been eliminated. Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in Gibbs free energy or chemical potential.

burning of fossil fuels?
Your questions can be answered by looking at the carbon cycle:
A total of 65 GTC of carbon is removed from the atmosphere annually.The combined quantity of carbon released from burning fossil fuels and soil is 69 GTC.What causes this result?The amount of carbon introduced to the atmosphere and the amount of carbon removed from the atmosphere within a certain period determine the amount of carbon present in the atmosphere during that time.
The total amount of carbon taken from the atmosphere equals the sum of the carbon extracted by oceans and plants. = 2 GTC + 63 GTC = 65 GTCThe total amount of carbon released into the atmosphere as a result of burning fossil fuels and soil is = 9 GTC + 60 GTC = 69 GTCThe carbon cycle is what?The carbon cycle explains how carbon is transferred from human sources to the atmosphere, soils, living things, the ocean, and the atmosphere again.

What is the average atomic mass of an element with two isotopes: 52.4% of isotope-
107 (mass=106.905) and 47.6% of isotope-109 (mass=108.905)
107 isotope (mass = 106.905): 52.4%; 109 isotope (mass = 108.905): 47.6% these two isotopes give these elements an average atomic mass of 107.856 amu.
A chemical element's isotope is any of two or more species of atoms that share the same atomic number, position in the periodic table, and virtually identical chemical behavior, but differ in atomic mass and physical characteristics.
There are one or more isotopes for each chemical element. An element's average atomic mass is calculated by adding the masses of its isotopes and multiplying each by the element's natural abundance.
The atomic weight of an element with more than one isotope is the average weight determined by the fractional abundance of all the isotopes.
Average atomic mass
= 0.5240(106.905) + 0.4760(108.905)
= 56.018 + 51.83
= 107.856 amu

how have the countries of origin for the largest immigrant groups changed since the beginning of the 20th century?
One of the ways that the countries of origin for the largest immigrant groups have changed since the beginning of the 20th century is politically. Wars such as WW1 have changed where more immigrants were coming from. For example, between the 1880s and the 1900s, there were an increase in immigrants. Larger groups included Russian Jews and Armenians from Eastern Europe.

or
space shuttle, also called Space Transportation System, partially reusable rocket-launched vehicle designed to go into orbit around Earth, to transport people and cargo to and from orbiting spacecraft, and to glide to a runway landing on its return to Earth’s surface that was developed by the U.S. National Aeronautics and Space Administration (NASA).
Answer:
A space shuttle is a reusable spacecraft designed to carry people and cargo into space and back to Earth. The space shuttle was developed by NASA in the 1970s and was in use from 1981 until 2011.
The space shuttle consisted of three main parts: the orbiter, which was the main spacecraft that carried the crew and cargo into space; the external tank, which held the fuel for the orbiter's main engines; and the solid rocket boosters, which provided additional thrust during liftoff.
The space shuttle was used for a variety of missions, including launching and repairing satellites, conducting scientific experiments, and building and servicing the International Space Station.
The space shuttle was retired in 2011, and NASA has since been working on developing new spacecraft for future missions to space.

It is the most fundamental, conventional, and often used of the various spatial reference systems in use. In addition, it forms the basis for the bulk of others.A GPS coordinate is made up of two components: latitude, which represents north-south position, and longitude, which shows east-west position. You may convert any address to its GPS coordinates using this map. Additionally, you can geocode any GPS coordinate's address and discover its location.The writing of latitude and longitude measurements varies.It has an angular unit of measurement, a datum, and a prime meridian (which contains the spheroid).Learn more about GPS here:
