Earth's Crust, Lithosphere and Asthenosphere - Windows to the Universe
Crust and Mantle vs. Lithosphere and Asthenosphere. Why do we use two names to describe the same layer of the Earth? Well, this confusion results from the. Outermost layer; thinnest under the ocean, thickest under continents; crust & top of mantle Middle layer, thickest layer; top portion called the asthenosphere. Differences between Lithosphere and Asthenosphere. Im contrasting the two layers. B. A poem that uses a strict pattern of rhyme and rhythm. C. A poem that is.
Very low temperatures are associated with icebergs, glaciers or icecaps; low to moderate temperatures are associated with the common types of precipitation like snow, rain, drizzle, sleet or hails; and high temperatures are tied to dry and hot conditions and evaporation.
The glaciers, icebergs, and icecaps are also categorically called the cryosphere. Biosphere Living Things All the living things in the planet are categorized under the biosphere. In this view, the biosphere includes all of the animals, plants, and microorganisms of earth.
Humans as well belong to this group. The entire ecological communities within the physical surrounding of the earth are within the umbrella of living things biosphere. These ecological communities interact together with the physical aspects of the earth including the hydrosphere, lithosphere, and the atmosphere.
Collectively, these ecological communities are made reference to as biomes. Deserts, forests, grasslands, aquatic, tundra, and chaparral are the six main biomes that are present in the biosphere.
- Differences between the Earths’ Lithosphere and Asthenosphere
The living things on earth interact with each other in various ways, which is well elaborated under the trophic levels of food chain — how energy is transferred in ecological systems. The surface of the lithosphere is uneven as it is characterized by various landform features.
Some of the landforms include mountains like the Mount Fuji in Japan and Mount Vesuvius in Italy, deep valleys within the mountain ranges, huge plains like the ones in Texas and Brazil, extensive plateaus like Bolivian plateau in South America and the Colorado plateau of the United States, and hills like the black hills.
The liquid, semi-solid, and solid land components of the lithosphere form layers that are chemically and physically different. This is why the lithosphere is further divided into sub-spheres namely the crust, the mantle, the outer core, and the inner core. The crust is made of loose soil and rocks.

The mantle is made of dense rock made up of nickel and iron in the form of silicate rocks and its lower part is semi-solid partially molten rocks. The outer core is made up of liquid purely molten rock materials. The inner core is the centre of the earth which is purely made of very hot and liquid iron and nickel.
The rock materials are divided into three primary categories based on how they are formed namely igneous rockssedimentary rocksand metamorphic rocks. When the molten rock extrudes, it cools, forming the new crust. Convection force also causes the lithosphere plates at the ocean ridges to move apart [vi]. Therefore, represents a rheological boundary, i.
What is Earth?
LAB depicts the transition from hot mantle in the asthenosphere to the colder and more rigid lithosphere above. The lithosphere is characterised by conductive heat transfer whereas the asthenosphere is a boundary with advective heat transfer [vii]. Seismic waves moving through the LAB, travel faster across the lithosphere than the asthenosphere. This is due to the different densities and viscosity of the asthenosphere. The boundary where seismic waves slow down is known as the Gutenberg discontinuity which is believed to be inter-related to the LAB, due to their common depths.
Continental lithosphere LAB depths are a source of dispute, scientists estimate a depth ranging from km to km. Ultimately continental lithosphere and the LAB in some older parts, are thicker as well as deeper.

Suggesting that their depths are age dependant [viii]. Comparison of the Lithosphere and Asthenosphere Lithosphere The lithosphere concept was proposed in The asthenosphere concept was proposed in Lithosphere is composed of the crust and upper most solid mantle Asthenosphere is composed of the upper most weaker part of the mantle Lies beneath the atmosphere and above the asthenosphere Lies beneath the lithosphere and above the mesosphere The physical structure consists of a rigid outer layer that is divided by tectonic plates.
It is regarded as rigid, brittle, and elastic.
