Kayla Biosphere - The biosphere is all about life. It describes our living world. This is where all the trees, bugs, and animals live. The biosphere is the one place where all the other spheres of the planet work together. The biosphere extends to any place that life of any kind can exist on earth. Many factors affect the biosphere and our life here on earth.
Atmosphere-The atmosphere is just a thin layer of gases that surrounds the earth. Without the earth's atmosphere, our planet would become extremely cold and barren of life. The atmosphere consists of 78% of nitrogen and about 21% of oxygen. The other one percent consists mostly of argon, carbon dioxide, and several "trace" gases such as neon and helium. Like the glass roof and walls of a greenhouse, the earth's atmosphere keep's its surface much warmer than it would be without the "greenhouse effect". The atmosphere begins at sea level, and extends outward some 6,000 miles into space. Gravity keeps the atmosphere very close to the earths surface.
Hydrosphere- In Latin "hydro" means water. The hydrosphere is the liquid water component of the earth. It includes the oceans, seas, lakes, ponds, rivers, and streams. The hydrosphere covers about 70% of the surface of the earth and is the home for many plants and animals. The hydrosphere, like the atmosphere, is always in motion. The motion of rivers and streams can be easily seen, while the motion of the water within lakes and ponds is less obvious. The oceans currents are also affected by the motion of the atmosphere, or winds above it. Interaction
Chelsey The End 75% How much of earths surface is covered by the Hydrosphere? How does the temperature and salinity of ocean water affect movement in the ocean? Temperature affects the density of the sea water. warming causes water to expand and become less dense. How are we able to study the ocean? Current meters
chemical test kids
pH meter
pH test strips
Sounder(lead line) A. Trophosphere: The layer closest to the earth. This is where the weather occurs and Greenhouse effects as well.
Stratosphere: Abovr the trophosphere. It extends 30-35 miles above the earth. The temperature rises within the stratosphere but will remain below freezing.
Mesosphere: From 35-50 miles above the surface. The air is very thin because the molecules are spread far apart.
Thermosphere: Extends 80 km above the earth's surface and is extremely hot. however there are few molecules present. What is the composition of the atmosphere?
The atmosphere is made of various gases that act as a protective shield and all life to exist on earth Crust-0-100km thick
outer cove 5100 km thick a. identify and describe the physical layers of the Geosphere. Crust-rock,dust,sediment
mantle-dense stone
outer cover-maten rock
inner cove-solid b. identify and describe the compositional layers of the geosphere. different elements, rocks, water, soil and other things
appear near the surface. c. what is the compesition of the crust? continental crust is generally move up of
granite and other sediments. and they are known to be 1500 million years old. oceanic crust tends to be near 200 million years old.consis of mostly basalt oceanic crust is thicker than the continental crust. d. how are continental crust and oceanic crust diffrent? natural and synthetic seismic waves.geaisist measure the time it takes to detail and other characteristics in order to estimate university and size. e. how are we able to study the interior of the earth below the crust? e. how are we able to study the interior of the earth below the crust? f. what is plate tectonics? g. how does the geosphere affect the magnetic poles of the earth? Choose three pairs of spheres and describe how the two interact. Choose three spheres and describe how all three interact together.
Geosphere, Hydrosphere, and the Atmosphere.
The Geosphere, Hydrosphere, and the Atmosphere all represent a part of the earth and how the earth is made up. The geosphere is made up of the earths crust. The hydrosphere is made up of the earths water. The atmosphere is made up of the earths oxygen. What is beyond the atmosphere?
Space is beyond the atmosphere How does the temperature fluctuate within the atmospheric layers?
Trophosphere - deviates with height (temp. decreases as height increases)
Stratosphere - Temperature rises yet still remains below freezing
Mesosphere - Warmer than in the stratosphere however the molecules are scarce so it would feel cold
Thermosphere - hot but the molecules are extremely scarce Identify the ozone layer and its location and function
The stratosphere containz the O-zone layer. This acts as a repellent to harmful UV rays from the sun Identify the ionosphere and its location.
It is in the layer of earth's atmosphere that is ionized by solar radiation. It is in the the thermosphere. How does gravity affect the atmosphere?
The greater the distance from the earth's core the less effect gravity has. What is barometric pressure?
The atmospheric pressure indericated by a barometer What is humidity?
The amount of water pressure in the air. The Biosphere is the section of earth in which the environment can prosper. In the Biosphere is where living organisms can prosper. The biosphere extends from several kilometers above the Earth's Surface and 8 km below the oceans surface. The Biosphere extends to any place where there are living organisms. A Biome is a particular ecosystem where as the biosphere is all ecosystems. Definition of the biosphere A place on earth where cold water is frozen solid. Cryosphere natural and syfrtient seismic waves geologist measure the time it takes to detect and other characteristic in order to determine density and size. the movement of earths crust around the mantle main causes of earthquakes and tsunamis. the inner core is solid and rotates inside of the outer core which is composed of marten iron rock and other high temperature metals. This rotation is what changes the poles an dis what draws magnetic fields in a certain direction.
