Space What is Earth? The earth is the 3rd planet from the sun between Venus and Mars. The earth is made up of several unique properties, characteristics, composition and they all affect the processes of the earth differently.
The earth is the 3rd planet from the sun between Venus and Mars. The earth is made up of several unique properties, characteristics, composition and they all affect the processes of the earth differently. Cumulatively, they are primarily grouped into biological living things and physical non-living things.
These spheres are further divided into various sub-spheres. According to radiometric dating and other sources of evidence, Earth formed about 4. Earth gravitationally interacts with other objects in space, especially the Sun and the Moon.
Hydrosphere Water The hydrosphere includes all the gaseous, liquid, and solid water of the planet earth. Most of the water in the atmosphere is in gaseous form and as it rises higher into the atmosphere it condenses to form clouds which fall back on earth as precipitation.
All the water in the hydrosphere is always in motion just like the atmospheric gases. The natural earth features depicting the hydrosphere are the rivers, streams, lakes, seas, oceans and the water vapor.
Glaciers, which are the slowly moving masses of ice, are also part of the hydrosphere.
Oceans carry most of the salty water while the majority of lakes and rivers carry fresh water. 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. 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. Atmosphere Air All the air in the atmosphere makes up the atmosphere. The higher the atmosphere, the thinner it becomes and this trait gradually moves towards space.
Other layers of the atmosphere include the troposphere, mesosphere, thermosphere, and the exosphere. These atmospheric layers exhibit different chemical compositions and temperatures, and the temperatures and chemical compositions widely vary within the different layers.Apr 14, · In this episode of Crash Course Kids, Sabrina talks about two of the four spheres that make up our planet; The Geosphere and the Biosphere.
What's in these spheres? The puzzle includes biological (living) pieces and physical (non-living) pieces. These four pieces are dependent upon each other. To make the study of the biological and physical elements of the Earth easier to understand, scientists separate these biophysical elements into four spheres.
Lets take a look at these four spheres of the earth in bit more detail to understand how they help make up the earth.
The natural earth features depicting the hydrosphere are the rivers, streams, lakes, seas, oceans and the water vapor. These ecological communities interact together with the physical aspects of the earth including the.
The Natural Spheres From the standpoint of Physical Geography, the Earth can be seen to be composed of four principal components: Lithosphere - describes the solid inorganic portion of the Earth (composed of rocks, minerals and elements).
The four spheres of Earth drive all of its processes and support life on our unique planet. Interactions of Earth's Spheres Quiz; Interactions of Earth's Spheres: Purpose and .
Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.
