Earth's outer layer is called lithosphere- the word which originated from two Greek words lithos and sphaeros, meaning rocks and sphere respectively.

If we talk about physical properties of lithosphere it is the part of earth on which we are living. comprising the uppermost part of the mantle and the crust, that is rigid solid and brittle.

Lithosphere can further be subdivided in different layers like crust, mantle, outer and inner core. Crust comprises the outermost layer of earth,

There are rocks of different types and densities found on earth, If we talk about continents, they are present of granite layer of crust. Crust is the only functional part of the earth's layers that enables the survival of life on it, and provides the living organisms with anchorage, shelter and food. Some important physical characteristics of lithosphere are:

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
