why aren't granite, copper, or petroleum found everywhere on earths surface
Answer: The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.
Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.
What is earth surface ?The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.
The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.
Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.
Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

What are the elements in group 1 of the
periodic table called?
Answer:
there called alkali metals
Answer:
alkali metals.
Explanation:
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
4. Which chemical formula below contains 2
different elements?
A. CO
B. Fe2O3
C. C2H4
D. All of the above
The chemical formula of CO, Fe₂O₃, and C₂H₄ contain atoms of two different elements. Therefore, option (D) is correct.
What is the chemical formula?A chemical formula provides information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be represented by using chemical symbols of elements, numbers (subscripts), and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.
A chemical formula of a compound has no words but can be written in certain simple chemical structures. Chemical formulae can be more limited in power than chemical names and structural formulae. There are two kinds of chemical formulas in which one empirical formula and another molecular formula.
In the chemical formula of carbon monoxide (CO) has carbon and oxygen two different elements. In the chemical formula of iron oxide (Fe₂O₃) iron and oxygen are two different elements. In the chemical formula of ethane (C₂H₄ ) has carbon and hydrogen two different elements.

Using the empirical formula, calculate the formula weight of the compound. Use the periodic table to help you.
Type the correct answer in the box. Round your answer to three decimal places.
Answer:
The formula weight of the compound is
46.069 g/mol.
Explanation:
Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:
molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.
What’s the difference between directly

Calculate the mass of one atom of sodium.
Use the equation:
relative atomic mass
mass of one atom of sodium =
Avogadro constant
Avogadro constant = 6.02 x 1023
Give your answer to 2 significant figures
Answer:
3.82 × 10 ^-23 g
Explanation:
6.02 x 10^23atoms = 1 mole of sodium
1 atom = 1/(6.02 x 10^23) mole
mass = mole × molar mass
= 1/(6.02 x 10^23) × 23
= 3.82 × 10 ^-23 g

4.6 billion years
6.4 billion years
8.2 billion years
Answer:
B : 4.6 billion years
Credits go to the person above me.
;)
Explanation:
EDGE 2021
The sun is about 4.6 billion years old. Therefore, option (B) is correct.
What is the sun made of?The Sun is made primarily of the elements hydrogen and helium. They account for 74.9% and 23.8% mass of the Sun in the photosphere. All heavier elements, called metals account for less than 2% of the mass, with oxygen (<1%), carbon (0.3%), neon (0.2%), and iron (0.2%) being the most abundant.
The hydrogen and helium in the Sun would have been produced by Big Bang nucleosynthesis and the heavier elements were produced by former generations of stars before the Sun was formed.
The amount of helium and its location within the Sun has gradually changed over the past 4.6 billion years. The proportion of helium has raised from about 24% to 60% due to fusion, and some of the He and heavy elements have settled from the photosphere toward the center due to gravity.
Therefore, the age of the sun is about 4.6 billion years.

What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

Aluminum has metallic bonds between its atoms. Which statement BEST describes the
valence electrons in aluminum?
are exchanged with nonmetal atoms
are exchanged with other metal atoms
are localized and stay between metal atoms
are delocalized and move between metal atoms
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.
