As altitude increases, the air density decreases. This is because as we go higher in the atmosphere, there is less air above us, resulting in lower pressure. The lower pressure causes the air molecules to spread out, leading to a decrease in density. This decrease in air density at higher altitudes has various effects, such as reduced oxygen levels, lower temperatures, and thinner air, which can impact human activities like breathing and aircraft performance.

Air pollution can have various health effects, including asthma, cough, and chest pains. These symptoms are commonly associated with exposure to polluted air. Asthma is a chronic respiratory condition that can be triggered or worsened by air pollutants. Coughing is a common reaction to irritation caused by pollutants in the airways. Chest pains can occur due to inflammation and irritation of the respiratory system caused by air pollution. Therefore, all of the options listed are potential health effects of air pollution.

A barometer is an instrument that measures air pressure. It is used to determine atmospheric pressure, which is the force exerted by the weight of the air above. This measurement is important in weather forecasting as it helps predict changes in weather patterns. A barometer typically consists of a glass tube filled with mercury or aneroid cells that react to changes in pressure. By measuring the height of the mercury column or the movement of the aneroid cells, the air pressure can be determined.

Altitude refers to the distance above sea level or the elevation. It is a measure of how high an object or location is in relation to the average level of the ocean's surface. It is commonly used to describe the height of mountains, buildings, or airplanes. Altitude is an important factor in various fields such as aviation, meteorology, and geography as it affects temperature, air pressure, and atmospheric conditions.

Air pressure is the result of the weight of a column of air pushing down on an area. As air molecules have mass, they exert a force due to gravity. This force creates pressure on the surface below, which is known as air pressure. The weight of the air column above a particular area determines the magnitude of the pressure. Therefore, air pressure is a measure of the force per unit area exerted by the weight of the air above it.

The volume can be calculated by dividing the mass by the density. In this case, the mass is given as 50 lbs and the density is given as 5 lbs/mL. Dividing 50 lbs by 5 lbs/mL gives us a volume of 10 mL.

A cumulonimbus cloud usually has an anvil top. Cirrus clouds are thin and wispy.

Farming is one human activity that causes large amounts of soil particles to enter the atmosphere. This is primarily due to the practice of plowing, which involves turning over the soil to prepare it for planting. Plowing can lead to soil erosion, where the top layer of soil is loosened and carried away by wind or water. As a result, soil particles become airborne and enter the atmosphere. This can have negative consequences such as reduced soil fertility, increased sedimentation in water bodies, and air pollution.

The correct answer is 4 g/mL because density is calculated by dividing the mass of an object by its volume. In this case, the mass is given as 100g and the volume is given as 25mL. Dividing 100g by 25mL gives us 4 g/mL, which is the density of the object.

The diurnal range will be greatest when the air is very dry.
