Why is the grass wet in the morning?

Answer 1

Of course grass is not always wet in the morning, only is certain atmospheric conditions are met. Given that 0500 more or less is the typically coolest time of the day, this is the most likely time that the air could become saturated with moisture and a mist could condense out and settle on the grass. The ground will actually be warmer than the air as it has higher heat capacity and warms or cools more slowly than air can. If your moisture level of the air is low then it is often the case that even at the coolest time of day there is no condensation. In desert regions the humidity can be real low and even though the air temperature in a desert can go to minus in the early hours of the morning, there is rarely dew. On the other hand if you are in a high humidity zone, close to the sea or river or lake for example, you can get a dew forming even in the evening and the air has a damp feeling to it.

Notwithstanding all this scientific explanation there could be another possibility. Your dog or some other animal has just peeed on the grass.

Answer 2

Due to the cooler temperature at night , condensation of Air takes place. This leads to the formation of water droplets. This water droplets get settled on the leaves and the Grass. This deopletes of water are called Dew and thus grass is wet.

Answer 3

usually in the mornings the temperature and the dew points are the same...when the temperature hits the dew points, condesation occurs therefore leaving dew on the grass. This is also why it is usually foggy in the morning or late at night.

Answer 4

As the grass gives of radiation, it cools. This cooling allows for the vapor pressure of water vapor in contact with it to decrease below equilibrium vapor pressure (dewpoint) and therefore condense. In addition to this, the air at night frequently cools which aids this process. This is called dew.

If the ambient temperature (regular outside temperature) falls below the dewpoint, then mist and possibly fog will form.

Answer 5

the vapor pressure of water decreases with temperature. this means that if water vapor in the air is in equilibrium with liquid water (in clouds for instance) and the temperature decreases, as it tends to at night, more liquid is formed.

Answer 6

it is dew
