lithosphere Earth's crust and a small portion of the upper mantle that make up Earth's plates. This layer of the Earth undergoes tectonic activity.
Local Group The small galaxy cluster that includes the Milky Way Galaxy.

LITHOSPHERE - Rigid outer layer of a planet. The base of the lithopshere is defined by the temperature at which the brittle/ductile transition occurs in the mantle.

Lithosphere: Layer in a planetary body consisting of the crust and upper mantle.
Longitude: The angular distance East or West, between the meridian of a particular place on Earth and that of Greenwich, England, expressed in degrees or time.

Lithosphere - The rigid outer layer of a planet or satellite, composed of the crust and upper mantle

The lithosphere and the aesthenosphere
The crust is thin, varying from a few tens of kilometers thick beneath the continents to to less than 10 km thick beneath the many of the oceans.

The solid part of a planet's surface, composed of the crust and upper mantle. On Earth, it includes the continents and the sea floor.
Local Group ...

The ~ is the solid, rocky, outer part of the Earth consisting of the crust and the upper mantle.

~ - (n.)
The layer in the earth, moon, and terrestrial planets that includes the crust and the outer part of the mantle.
local group - (n.) ...

The ~ has the following abundance of elements:
46.60% oxygen, 27.72% silicon, 8.13% aluminium, 5.00% iron, 3.63% calcium, 2.83% sodium, 2.59% potassium, 2.09% magnesium, 0.44% titanium, 0.14% hydrogen, 0.095% manganese, 0.070% phosphorus, 0.065% fluorine, 0.026% sulfur, 0.025% carbon, 0.

The ~ essentially floats on the asthenosphere and is broken up into what are called tectonic plates. These plates are rigid segments that move in relation to one another at one of three types of plate boundaries: convergent, divergent and transform.

Beneath the ~ is the asthenosphere, a relatively low-viscosity layer on which the ~ rides. Important changes in crystal structure within the mantle occur at 410 and 660 kilometers below the surface, spanning a transition zone that separates the upper and lower mantle.

~ The solid part of the earth or other spatial body. Distinguished from the atmosphere and the hydrosphere. See geosphere, biosphere. live testing The testing of a rocket engine, vehicle, or missile by actually launching it. Compare static testing.

~ Stony crust and upper mantle of Earth to an approximate depth of 50 kilometers. Local Group Small group of bunched galaxies, including our Galaxy, consisting of about 20 known members spread over a diameter of about three million light years.

The upper mantle is rigid and is part of the ~ (together with the crust). The lower mantle flows slowly, at a rate of a few centimeters per year. The asthenosphere is a part of the upper mantle that exhibits plastic properties.

tectonism (Galileo Project Glossary - JPL) The processes of faulting, folding or other deformation of the ~ of a planetary body, often the result of large-scale internal movements below the ~.

This allowed an altimetric map to be made, which can be used to constrain the morphology of large basins and other lunar features, study stress and strain and flexural properties of the ~, and can be combined with gravity to study the density distribution in the crust.

When oceanic crust runs into oceanic crust or into continental crust, the denser ~ material slides under the less dense ~ material and melts in the asthenosphere. The region where the ~ pieces contact each other is called a subduction zone and a trench is formed there.

The weight of the redistributed surface mass loaded the ~, causes it to flexure and also induced stress within the Earth. The presence of the glaciers generally suppress the movement of faults below (Johnston 1989, Wu & Hasegawa 1996, Turpeinen et al. 2008).

Plate tectonics is a theory dealing with the dynamics of the Earth's outer shell, the ~. Resting on a broad synthesis of geologic and geophysical data, it dominates current thinking in the Earth sciences.

Plate tectonics describes the large scale motions of Earth's ~. The theory encompasses the older concepts of continental drift, developed during the first decades of the 20th century by Alfred Wegener, and seafloor spreading, understood during the 1960s....

The crust is part of the ~ and is located above the mantle. You might be interested to know that there are actually two types of crust, and they are sort of like pizza crusts. No, they aren't filled with cheese or anything silly like that - they just have different thicknesses.

The geomagnetic field is generated by convection in the liquid outer core, plate tectonics are a process that occurs in the ~ (which comprises the crust and the outer region of the mantle).

crust -- The outermost layer of the ~.
cuspate -- Shaped like a cusp; a sharp projection of material.
Dactyl -- In Greek mythology, a legendary being that lived on Mount Ida.

Large sections of the Earth's ~ that move as single units.
refers to "poor cluster of galaxies;" a cluster of galaxies with very few members; a group of galaxies.

There is a high correlation between gravity and elevation, so topography might appear to be supported by a strong ~. Venus's high surface temperature, however, makes this unlikely. Instead, it is possible that convection creates upwellings which deform the surface.

The crust is the outermost layer of the ~ (the solid part of the Earth consisting of the crust (broken into plates) and the upper mantle).

He argues that the definition of a life inhabited biosphere is "self-aggrandising nonsense" and that the term ‘biofilm' is more accurate: a tenuous, incredibly thin veneer on the outside of a planetary crust (the ~) that life can gain energy from to survive.
