Droplets of sweat were welling up on his forehead.

As muddy sediments are pressed together, the gas and small droplets of oil may be squeezed out of the mud and may move into sandy layers nearby.

When photons and light waves hit objects in our atmosphere, water droplets, oxygen and nitrogen molecules, dust particles and so on,

It attracts the water droplets, sucking them into the tiny pores.

What happens is they cause the tiny water droplets to flatten when they condense on the surface of the shower door or bathroom mirror or whatever object it is, it's been applied to.

Light hits the water droplets and is scattered in random directions, causing the fogging effect.

These seeds are actually chondrules: millimeter-sized melted droplets of silicate material that were cooled into spheres of glass and crystal.

And the sulfur dioxide settled in the clouds fell to the land in droplets of rain and sank into the soil.

And that alters the shape of the droplets.

Now, what's actually happening is, what the fog is, is thousands of tiny spherical water droplets condensing on the surface of the glass.

Depending on the location, time of year, and time of day, any or all of the following differences between cities and their surroundings can be important: albedo (reflectivity of the surface), surface roughness, emissions of heat, emissions of moisture, and emissions of particles that affect net radiation and the growth of cloud droplets.
