Why is it important to know how the sun's energy affects the lower atmosphere if you are planning to harness the power of moving air?
Answers
It is important to know the affects of temperature on pressure and thereby on winds. At high temperature, the pressure will be high and thus, the winds will pass from that area.
What is winds?
Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.
Air pass from high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.
Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.

Answers
Answer:
40.3 for the unit that represents the minimum amount of magnesium oxide I beilieve.
Explanation:
Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. Taking just one atom of Mg and one atom of O you will get a mass of 16.0 + 24.3 = 40.3.

What makes up fog? What happens to the water molecules that cause them to turn from fog into rain?
Answers
When the water vapors condense and water molecules combine to make tiny water droplets in the air is known as fog. The precipitation of fog when the humidity of the fog attains 100% and begins to unite into larger droplets or rain.
How is fog formed?Fog is the tiny water droplets suspended in the air at or near the Earth's surface. Fog is a type of low-lying cloud and is heavily influenced by nearby bodies of water and wind conditions.
When the environment is very humid then Fog happens. The air around the surface of the earth can hold a certain amount of water vapor in a gaseous state. As more water fills the air, the air becomes more humid is known as humidity.
Water vapor unites to make tiny liquid water droplets that hang in the air during the condensation of the water molecules. Water vapor is a gas and invisible but the fog can be seen with our eyes. The fog turns into rain when the humidity is almost 100% by combing into larger droplets.

How do gases in Earth's atmosphere keep the amount of energy that Earth receives from the sun from being too much, or more than Earth and its organisms can tolerate?
Answers
Answer: The gases help shield the Earth from harmful UV rays that could damage life on it. They also help prevent extreme day and night temperatures.
Explanation:
The atmosphere is a gaseous layer or the blanket of the gases that surrounds the planet and is held at a place by gravity. It is essential as it comprises various gases needed to maintain the temperature and the climate of the planet.
What is the role of the atmosphere?The atmosphere is crucial for life to be maintained on the planet as it balances the amount of the sun rays and heat to enter and exit the planet's surface and environment.Various gases like nitrogen, carbon dioxide, oxygen, neon, helium, methane etc. are essential as plays an important role in blocking the harmful ultraviolet rays from the sun and traps a certain amount of heat to maintain the temperature of the planet.Thus, protection and maintaining temperature is the role of the atmosphere.

What do you have to change in order to change the motion of an object? (2 points) a Distance b Duration c Speed d Time
Answers
Answer:
123456789890-0-------plmnbvzxcvdasdgf
:]
Explanation:
To change the motion of an object, you will change its: Speed and time. Option C and D is correct.
Changing the speed of an object will alter how fast or slow it moves. Increasing the speed will make the object move faster, and decreasing the speed will make it move slower.
Changing the time over which the object is in motion will also affect its overall motion. For example, if an object covers a certain distance in a shorter time, it will have a higher average speed compared to covering the same distance in a longer time.
By modifying the speed or time, you can change the motion of an object, making it move faster or slower or for a longer or shorter duration. Changes in distance or duration may also indirectly impact the motion, but speed and time are the primary factors directly affecting an object's motion.
Hence, C. D. is the correct option.
