Some minerals are evenly distributed around the planet, while other minerals are quite rare. Why are some minerals so rare and unevenly distributed?
A. Certain minerals form only under high heat and pressure that develop near volcanoes.
B. Certain minerals form only in Earth's crust, so they are difficult to locate.
C. Certain minerals form only in specific climates, and not all climates, are the same around the world.
D. Certain minerals form only in the extreme heat found at the bottom of lakes and rivers.
Please answer with an explanation THAT ISNT a browser answer you just copied pls
Answer:
A.
Explanation:
certain minerals form only under high heat and oressure that develop near volcano. That is why minerals vary among areas.
The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.
What are minerals?A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.
Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Form a hypothesis that explains your choice. You will be able to revise your hypothesis after performing experiments.
Hello. You have not informed the experiments to which the question refers, which makes it impossible for hypotheses to be formed. However, I will try to help you in the best possible way.
A hypothesis is an assumption, that is, it is a statement that the researcher believes to be true in relation to the research results, which can be proven or denied when the experiment is finished and the conclusions are established. Therefore, you must make assumptions about the results of the experiment, based on your primary visualization of them.
In the tundra, what is the difference between the biotic and abiotic factors you saw in the image?
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. ... Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.
Explanation:
Biotic is living part whereas abiotic is non-living part of an environment.
The main difference between biotic and abiotic factors is that biotic factors refer to the living part or component of environment such as plants, animals etc whereas abiotic factors refer to non-living part of the environment such as temperature, humidity and light etc. Both biotic and abiotic factors depends on each other for their survival so we can conclude that biotic is living part whereas abiotic is non-living part.

Answer:
Although the rat liver is typically lobated2 and its ap- pearance does not resemble that of the human liver, the hepatic lobes of the rat liver have been found to be equivalent to the sectors of the human liver. As rats and humans belong to the class Mammalia, similar em- bryological development is expected.
