What type of heat transfer is most important to maintaining a relatively stable
climate on Earth? Justify your answer.
The type of heat transfer that is most important to maintaining a relatively stable climate on Earth is known as solar radiation.
What is Heat transfer?Heat transfer may be characterized as the migration or transmission of heat across the border of the system due to an imbalance of difference in temperature between the system and its surroundings.
Solar radiations govern the principle and the entire process of heat transfer because it is the principle and fundamental source of heat and energy for the entire planet of the earth. These radiations initiate the process and pass down to the source artificial sources of heat transfer in physical life.
Therefore, solar radiation is a type of heat transfer that is most important to maintaining a relatively stable climate on Earth.

Answer: 444.5N (Newtons)
By looking at the relative positions of the elements calcium, Ca, fluorine, F, sulfur, S, and oxygen, O, in the Periodic Table, which TWO descriptions are TRUE about calcium fluoride, CaF2, and sulfur dioxide, SO2?
CaF2 is an ionic compound, and SO2i is a covalent compound.
CaF2 is formed by covalent bonds, and SO2 is formed by ionic bonds.
CaF2 cannot conduct electricity when dissolved in water, but SO2 can.
CaF2 is a gas at room temperature, while SO2 has a high boiling point.
CaF2 has a high boiling point, while SO2 is a gas at room temperature.
CaF2 is soft at room temperature, while SO2 is hard and forms crystals.
Answer:
Calcium Compunds-The fluoride,CaF²,is important to the production of hydrofluoric acid,Wich is made from CaF² by the action of sulfuric acids.CaF² us used laboratory instruments as a window material both infrared and ultraviolet radiation.
Sorry if other question not answeredCalcium Compunds-The fluoride,CaF²,is important to the production of hydrofluoric acid,Wich is made from CaF² by the action of sulfuric acids.CaF² us used laboratory instruments as a window material both infrared and ultraviolet radiation.
Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.
Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.
Calcium Fluorine is a naturally occurring element that is frequently found in rock, soil, plants, and animals.

Use the phrases building up and breaking down to explain how deposition differs from weathering?? I did this for class today the rest of the worksheet but I didn't get this one could someone help me please.
Answer:
Explanation:
Weathering is the breaking down of rocks into smaller pieces and deposition is the building up of some kind of natural structure using erosion. So basically its rocks moving around to create bigger, better rocks.

Answer: Streams and rivers are integral parts of the landscape that carry water and sediment from high elevations to downstream lakes, estuaries, and oceans. The land area draining to a stream or river is defined as its watershed. When rain falls in a watershed, it either runs off the land surface, infiltrates into the soil, or evaporates.

explain how you can recognize the sound of a flute
The sound of a flute is poetic, light, mellow, and soft. Flute is a woodwind musical instrument produces the mild sound.
How flute produces sound?Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as solid, liquid ang gases. When an object vibrates, it causes a movement in surrounding air molecules. The molecules collide with the molecules close to them, causing them to vibrating as well.
The sound from flute comes due to the vibrating columns of air inside it. In a flute, the air gets vibrated and the resonator amplifies the vibration and gets modified into sound. When air is blown into the holes of flute, it creates the vibration in the air molecules inside the flute and hence, sound is produced.
The flute can produced continuous sound by the presence of number of holes in it. The flute sounds may be high pitch or soft tone depends on the position of upper and lower lips on flute.The sounds of flute are rich, gentle and gracefull.

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.
Which explains how she can prove her theory?
A
She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.
B
She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.
C
She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.
D
She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.

On a particular day, Denali had a temperature of -23°C at its peak and 13°C at its base. What could be the reason for this temperature difference?
A.
Temperature increases with an increase in altitude.
B.
Temperature decreases with an increase in altitude.
C.
The base is close to the Gulf of Alaska.
D.
The mountain receives lake-effect snow.
Answer:
B.) Temperature decreases with an increase in altitude.
As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard average lapse rate.
