How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.
The answers are in the picture. this us the question, An increase in carbon dioxide production has led to an increase in global temperatures, which is causing glaciers to melt faster. If this trend continues, how will animals living in the polar regions be affected?
Answer:
D
Explanation:
because if there is no land for them they wont survive in only water
The increase in global temperature melts the ice in polar regions. This worsely affects the animals living there. Hence, they will migrate to other areas but this is in fact not possible for their adaptation in other areas and they may subject to extinction.
What is global warming ?Global warming is the rise of temperature of earth surface all over the world. The significant reason for global warming is green house effect. Gases like carbon dioxide, methane gas etc. are intensely absorbing temperature that is radiating back from earth.
Hence, these gases are increasing the atmospheric temperature in earth. Global warming have very serious impacts that going up to the major discussion to solve nowadays.
The melting of polar icebergs and rising of sea level definitely leads to the extinction of animals living in polar region. They cant be adopted to other regions and migrating to other areas does not save them. Hence, they will extinct from earth. Therefore, option d is correct.

Which of the following is an example of an adaptation that might be useful in the grassland? HELP ME PLS
A. an insect looking like a tree branch
B. an animal having a heavy coat of fur
C. an animal having large feet so it can walk on the snow
D. an animal being the color of brown grass and dust
Answer:
D
Explanation:
In the grassland pretty warm so the heavy fur coat wouldn't help, there is no snow in the grassland so the big feet for walking on snow also wouldn't help, its the grassland where trees are more scarce so not A, but there is a lot of grass and dust so being able to blend in would help.

Explanation:
Warm and cold air fronts with points labeled 1 through 4, cold air entering from the left and moving down. Therefore, the correct option is option 1.
What is air?The term "air" is used to refer generally to the concoction of gases that composes the Earth's atmosphere. Nitrogen makes up the majority of this gas (78%), with oxygen, water vapor, argon, carbon dioxide, and trace gases also present.
There is no color or smell in pure air. Dust, pollen, and spores are common airborne contaminants; additional pollutants are alluded to as "air pollution." Since there isn't air in space, the so-called air on another planet, like Mars, would have different manufacturer. Warm and cold air fronts with points labeled 1 through 4, cold air entering from the left and moving down.

9. Scientists are studying cellular respiration in a jungle ecosystem that has plants,
animals, and decomposers (which consume dead things). Which group or groups of
organisms in the jungle carry out cellular respiration?
plants
animals and decomposers
all organisms in the jungle
animals.
Answer:
all organisms in the jungle
Explanation:
Scientists are studying cellular respiration in a jungle ecosystem that has plants, animals and decomposers, so all organisms in the jungle carry out cellular respiration.
What is cellular respiration?Cellular respiration is a process in which organism use the oxygen molecule for the conversion of their food materials to get the chemical energy by the product of water and carbon dioxide.
This respiration process is done by all living organism like plants, animals, insects, bacteria, etc. to get energy for the other cellular functions. So, in the ecosystem of jungle plants, animals and decomposers all will perform cellular respiration.
Hence, option (c) is correct i.e. all organisms in the jungle.

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.
What is metal ?A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.
These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.
The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.
Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

How many moles are there in 17.6g NaOH?
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.
Mathematically,
number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH
Molar mass of 1 mole of NaOH= 40 g/mol
mass of NaOH= 17.6g
Substituting all the given values in the above equation, we get
number of moles of NaOH = 17.6g ÷ 40 g/mol
number of moles of NaOH =0.44moles
Therefore, 0.44moles are there in 17.6g NaOH.
