Hello there!! I am grateful for your visitation of my first ever blog.The purpose of this thread is to obtain the skills of creating a blog website of each students and to gain knowledge in a subject (E-Tech).I hope you will support me and to share this information to everyone and to suggest comments below. This would be a great help for me in my studies.God Bless and enjoy!
FOUR SUBSYSTEMS OF EARTH
Several studies were conducted in examining the earth's structure and analyzing the different functions of each sphere.These following informations explains the interaction of each spheres to another one and how it works together to sustain earths functionality.
GEOSPHERE
First form that creates the earths component is the Geosphere,
This Sphere serves as the major matter that composes the earths structure. This is where we stand, and below it, the geothermal activity is constantly occurring and from time to time, it affects the earth's surface and results the land formation and volcanic eruptions. These earth disturbance is the reason of the sliding of earth's continents.
Geographers were stunned about these events until they found out that earth crust is divided into three major layers, the crust mantle and core.
The crust is the outermost part of the earth's land and it is the thickest.
The mantle is in the middle part and the thickest.
The core is the innermost part and it has the hottest temperature.
HYDROSPHERE
The major form that perdures life on earth is the Hydrosphere. It poses a great role in the earth's system as it nurtures the land fertility and gives energy to the animals. Almost all living organisms needs water and this is why it is important the earth's function. It also keeps tge earths moderate temperature in dry season.
Hydrosphere is composed of saltwater and freshwater. The saltwater has the greater amount while the freshwater is is only few in a total part.
In earth's surface, Hydrospher had taken the biggest part since there are only few percent in continents. This sphere also has its own biodiversity where land creatures can seize food.
ATMOSPHERE
Atmospher is the outermost part of earth where it is composed of a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth.
Atmosphere is divided into five parts, the Troposphere, Stratosphere, Mesosphere, Thermosphere and the Exosphere. Each part had unidentical temperature that traps different harmful gases.
It is the sphere where there are few living things can approach. Althouch it is far enough, this also poses a great role in earth system. It is where different climates occur and gives oxygen to the animals on earth.
The Atmosphere also serve as coating and protection from the strong heat of the sun.
If this sphere is being desolated, it will no lonher handle heat and will trap suffocating gases that will increase earth temperature and would result into global warning.This part should be handled well because of its delicate structure.
BIOSPHERE
The Biosphere is the product of the said spheres. It is where living things are categorized. If one of each earth's subdivisions were lost, life is impossible to exist in the planet. A small community of living thing is called Biodiversity
Physical geographers use the term biosphere to describe our living world. All of the microbes, plants, and animals that inhibits the planet are part of the biosphere.
Biologist continues to study the evolution of the living things and how they are able to adapt the earth upto the present. They formulated the age of animal fossils in order to determined their extinction and to know what woul id help to the future.
These Four Major Subdivisions of earth are equally important in the making of the earth's functionability. Without these subsystems, life is impossible to exist.We should take care of each system to maintain the life on earth.
