Answer:
The water is under pressure naturally and no pump is needed.
Explanation:
C
The water in artesian wells is under natural pressure and requires no pump.
What are artesian wells?They are wells that contain water that is under natural flowing pressure. Thus, there is no need of using artificial pumps in order to get the water to the surface.
Artesian wells are dug on lands with special geological features that enable the water to flow out under natural pressure.
Artesian wells differ from other types of wells that require mechanical or electric pumps before the water can get to the surface.

What patterns in the rock layer fossils helped you identify an extinction?
Answer:
Hope this helps!! :D
Explanation:
Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

“The use of fossil fuels by human’s is heating up the atmosphere” is an example of a law or theory? Explain your answer in at least 3 sentences.
Answer: Theory
It is a theory which is true because it is not a law. A theory by definition is “ a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena.” A law is “a rule defining correct procedure or behaviour in a sport.“ Therefore since this a scientific fact and it is used/ not against the law it is a theory

How do the light rays emitted by a candle travel?
Answer:
Explanation:
The light rays coming from the unlit candle and the reflected light rays of the lit candle are superposed on top of one another. ... For very transparent substances like glass, only about 5 percent of the light that hits it is reflected. The remaining 95 percent is transmitted—it passes right on through.

In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.

describe what is happening to rock climbers’ body systems and cells at the small scale.
Answer:
It is being pressured!
Explanation:
The pressure point changes so people aren't used to that certain pressure
As a rock climber climbs higher, the systems and cells experience a decrease in pressure.
Pressure decreases with height. Hence, the higher you go, the lesser the pressure becomes and this may have obvious implications on the cells and systems of a rock climber.
As air pressure decreases at higher altitude, a rock climber may find it difficult to breathe because of the sudden decrease in air pressure hence the respiratory system is affected.
Prolonged exposure to high altitudes may lead to a decrease in the amount of oxygen in blood causing the heart to pump harder.

What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

If two people attempt the same maneuver, what determines the amount of force that each is required to exert?
Answer:
Explanation:
you need to change either the turn of the jump or push off higher or lower from the wall
If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.
The amount of force exerted by each person is given by Newton's second law of motion, which states that the force exerted by an object is directly the proportional to the product of mass and acceleration of the object.
F = ma
where;
F is the applied forcem is the mass of the objecta is the acceleration of the objectThus, If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.
