Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both. The water and ice scatter all light, making clouds appear white. If the clouds get thick enough or high enough all the light above does not make it through, hence the gray or dark look.

condensation

Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

Fill about 1/3 of your jar with the hot water. Quickly remove the lid, spray some into the jar, and quickly put the lid back on. You should see a cloud forming. Watch what’s happening inside the jar, the air is condensing, creating a cloud.

Clouds are made up of hydrogen and oxygen molecules. They consist of water vapor. The higher the clouds are, that will mean that the clouds are comprised of tiny ice particles. Clouds would just feel like moisture.

Clouds smell liek smoke mixed w/ coffee mixed w/ pastries and Olde British Fish and chips cooking. so yummy as well as some deisel in the early morning. Clouds smell like wht is cooking at the period in time and the scent is rising.

Petrichor is the term coined by Australian scientists in 1964 to describe the unique, earthy smell associated with rain. It is caused by the water from the rain, along with certain compounds like ozone, geosmin, and plant oils.

Due to solar radiation, surface ocean water warms up and evaporates into the atmosphere. The water vapour is transported by the ascending air currents to altitudes where low temperatures condense the steam into water droplets or ice crystals that form clouds.

Quick Facts: A fishy smell can be caused by naturally occurring organic material in the earth like Barium or Cadmium metals. Chloramine is a compound of chlorine and ammonia used to disinfect public water sources. Unfortunately, it can cause an unwanted fishy odor in your water.

The rain smell’s actual name is petrichor, coined by two Australian scientists in the 1960s. Scientists say it’s a combination of ozone, petrichor and geosmin. Before it rains, a person might say that they can smell the storm coming. Their nostrils might be picking up the scent of ozone, or O3.

The air in the forest smells good. It may smell like damp moss, rain, wet tree trunks, flowers, and needle-covered path. It may smell like a tree stump that is already creating new life, or even snow, frost, and softwood.

That means human noses are 200,000X more sensitive to geosmin, which is also the source of the earthy taste in some vegetables, than a shark is to blood.

A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids.

Sharks can smell blood from up to around a quarter of a mile away. When you smell something in the air, it’s because scent molecules have dissolved into the wet lining of your nose.
