Layer

This process actually makes the outer layer waterproof.

Traditionally, fish and chips were wrapped in greaseproof paper and a thick layer of newspaper which served not only as an insulator but also as a plate to make eating outdoors easier—because of health and safety control, however, chippies are no longer allowed to use paper anymore.

It is surrounded by a deep layer of metallic hydrogen, then a layer of liquid hydrogen and liquid helium and finally, an outer gaseous layer.

This can occur when the fog layer is lifted and cooled sufficiently, or when it is forcibly compressed from above by descending air.

The thickness of a fog layer is largely determined by the altitude of the inversion boundary, which in coastal or oceanic locales is also the top of the marine layer, above which the air mass is warmer and drier.

The marine layer, and any fogbank it may contain, will be "squashed" when the pressure is high, and conversely, may expand upwards when the pressure above it is lowering.

Snow affects ecosystems, as well, by providing an insulating layer during winter under which plants and animals are able to survive the cold.

Due to the thick layer of fen and clay present in the soil of the city, all the city's buildings were erected on wooden poles that are fixed into a sandy layer of the ground over 35 feet deep!

The operating system (like Mac OS, Microsoft Windows, Android and various Linux distributions) is a layer of software that is used as a platform for running the applications, and controls all user interface tools including display and the keyboard.
