What does the "lithosphere" refer to? The biosphere is the narrow zone where we find land, water and air together. Crust. Hydrosphere is the water masses of the earth crust which include rivers, oceans, seas, lake, and glaciers underground water in the lower atmosphere. As tectonic plates move past each other along fault zones, they sometimes get stuck. The Earth itself is split into several layers: the crust, upper and main mantle, the outer core and the inner core. Recall that margin refers to the boundary between a continent and the ocean. It is about 55 km (34 mi) thick beneath the oceans and up to about 200 km (124 mi) thick beneath the continents. Refers to any natural hazard or threat that causes fatality or damage to property.

However, magma refers to molten rock below Earth's surface, and lava refers to molten rock at Earth's surface. [3] Since space exploration began, it has been observed that the extent of the ionosphere or plasmasphere is highly variable, and often much larger than previously appreciated, at times extending to the . what does the term 'Lithosphere' refer to. The lithosphere is the brittle outer layer of the solid Earth. Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements. It is covered by a thin layer of soil. 10. The Earth can physically be described as a ball of rock (the lithosphere), partly covered by water (the hydrosphere) and wrapped in an envelope of air (the atmosphere). Lithosphere, atmosphere, hydrosphere and biosphereare the four components from which earth is formed. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. The plates of plate tectonics are segments of the lithosphere. Lithosphere Layers of the lithosphere. Simply typing "lithosphere" into a web browser would bring you lots of information. Question 18. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. lithosphere, and hydrosphere. a. Oceanic crust c. mantle d. lithosphere b. asthenosphere 43. Lithosphere, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle. …. Lithosphere is being consumed at convergent boundaries . To these three physical zones, it is convenient to add a biological zone which includes all the living organisms (the biosphere). The atmosphere refers to the gaseous layers which surrounding the earth. refers to the highly localized transfer of water from plants and soils to the atmosphere and back. It is made up of rocks and minerals. It consists of a mixture of various gases and is believed to extend about 10,000 km above sea level. The lithosphere, Greek for "rocky sphere," is the outermost shell of the Earth. Isostasy. Without any one of them, we could not survive as a planet. Outgassing refers to. Atmosphere Definition Atmosphere refers to the gases surrounding a star or planetary body held in place by gravity. The solid lithosphere is thus floating on the fluid asthenosphere. It is made up of rocks and minerals and covered by a thin layer of soil. Continental lithosphere is associated with continental crust which covers the Earth's landmass. . B) Crust of the earth. (1 point each) 1) West margin of Africa a. passive b. active 2) East margin of South America a. passive b. active 3) West . 1. The biosphere is the zone of the earth and adjoining parts of the atmosphere in which plants and animals exist. In fact, it also includes all the rocks under the sea and under the surface of the Earth. True. The atmospheric temperature falls with rise in altitude, but it may reach beyond 1000°C above 500 km in exosphere (or thermosphere). The outer layer, the solid layers, the lithosphere sphere. The lithosphere is broken into tectonic plates (lithospheric plates), and the movement of these tectonic plates cause large-scale changes in the earth's geological structure (folding, faulting). kiruha [24] 6 months ago. c. Refers to endogenous and exogenous processes. it is the thinnest and the outermost layer of the earth's interior. Important Note : hydrosphere is the layer of the earth that holds water in both solid and . Plate tectonics refers to the scientific theory that describes the motions of seven large plates, as well as the movements of countless smaller plates that make up the Earth's lithosphere. The Earth is made up of roughly a dozen major plates and several minor plates. Crust and lithosphere refer to the same layer of the Earth. The hydrosphere refers to the water bodies that exist on the earth's surface. The lithosphere is a / an _____ surface. The term is also used to refer to the outermost rocky shell of other solid planets. Lithosphere is the solid crust or the hard top layer of the earth. The Lithosphere The lithosphere, sometimes called the geosphere, refers to all of the rocks of the earth. Lithosphere: refers to the outermost surface of the Earth, the Earth's crust.

Earth's Lithosphere can be best defined as a solid shell or a crust that protects the earth. Lithosphere consists of the solid crust or the hard top layer of the earth. The brittle lithosphere responds by producing normal faults where blocks of continental lithosphere are uplifted to form grabens or half grabens. It is a relatively thin layer, about 31 to 62 miles (50 to 100 km) thick under the oceans and 93 miles (150 km) thick on the continents. Note # 1. A) Interior of the earth. It refers to large seismically generated sea waves caused by Earthquakes, submarine explosions, and landslides. We can distinguish the crust and upper and mantle on the basis of chemistry and mineralogy. The atmosphere, hydrosphere, and lithosphere interact with each other to make our planet liveable. The lithosphere is the solid, outer part of the Earth. The lithosphere is made up of all the hard and solid land mass on the earth's surface, the semi-solid rocks (molten materials) underneath the earth crust, and the liquid rocks in the inner core of the earth. The lithosphere is found all around us and we interact quite closely with it every day. c. inner core a. Continental crust d. oceanic crust b. asthenosphere (pls also include the number 36- 39) the barren soil (lithosphere) becomes more susceptible to erosion, and the highly erodible soil gets washed into streams (hydrosphere) where it chokes aquatic organisms (biosphere). The plates can be thought of like pieces of a cracked shell . The lithosphere is the tectonic plate we talk about in plate tectonics. To help explain how the lithosphere is floating on the asthenosphere, we need to examine the concept of isostasy. Interactions occur between the four spheres. Answer: B) Crust of the earth.
