Four Spheres Part 1 (Geo and Bio): Crash Course Kids #6.1

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? How do they affect us? How do they fit into the puzzle that is Earth? All is contained within!

This first series is based on 5th grade science. We're super excited and hope you enjoy Crash Course Kids!

///Standards Used in This Video///
5-ESS2-1. Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact. [Clarification Statement: Examples could include the influence of the ocean on ecosystems, landform shape, and climate; the influence of the atmosphere on landforms and ecosystems through weather and climate; and the influence of mountain ranges on winds and clouds in the atmosphere. The geosphere, hydrosphere, atmosphere, and biosphere are each a system.] [Assessment Boundary: Assessment is limited to the interactions of two systems at a time.]

The Earth System

This video describes the four main components of the Earth system (atmosphere, biosphere, geosphere, hydrosphere), how matter is exchanged between the components, and how a change in some aspect of one part of the system will result in changes in other system components. We describe the Earth system in terms of reservoirs and flux between them and discuss how the movement of carbon occurs between system components.

Earth's Spheres For Kids | Geosphere, Hydrosphere, Biosphere, Atmosphere | Grades 3-5 Science Lesson


In this lesson, Dr. Jeff, Izzy and Zoe help you learn about earth's four spheres: the geosphere, biosphere, atmosphere and hydrosphere. These four subsystems of our planet contain everything on the planet. Most importantly, these systems interact to effect earth's processes. This educational video is for kids in 3rd, 4th and 5th grade. To watch the full lesson in class, tell your teacher to signup for Generation Genius :)

Earth systems - interaction

describe what system is having an effect on what system
1. Trees giving oxygen during photosynthesis
2. An Earthquake creating a Tsunami
3. Rabbit digging into the ground to build its home.
4. Strong winds destroying trees in a forest.
5. Pollution in the air cause people to suffer asthma.
6. Volcanoes erupting carbon dioxide into the air.

Big Idea 5: Earth is the Water Planet

Earth Systems

Geosphere, biosphere, hydrosphere, atmosphere


The Earth is a mighty big place y’all.
All kinds of things in and on and around
They have names too
Let me tell you how the 4 spheres of the Earth get down

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but let me be clear…er

The geosphere is what we call the land
We’re talking rocks, minerals, heavy metals, and sand
It’s the parts that are solid when we try to stand
We’ve experienced this sphere ourselves firsthand

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but let me be clear…er

Next up is the biosphere- that’s all life on Earth
The things that came about from some kind of birth
Whether from a mother or the inside of a seed
Living organisms that have definite needs

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but let me be clear…er

The hydrosphere is easy if you know hydro means water
Like in Finding Dory with the cute little otters
We’re talking lakes and rivers, oceans and streams
Floating like a jellyfish in saltwater dreams

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but let me be clear…er

Last but not least is the atmosphere
The gases that surround Earth aka the air
78% is nitrogen
21% is what we need: oxygen
And 1% is all the other gases
It’s breathable down low for the masses

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but let me be clear…er

Repeat after me y’all

Geosphere, biosphere, hydrosphere, atmosphere
It’s mouth full but NOW WE’RE CLEAR!

A brief overview to the area of Earth Systems Science where we will be looking at the different spheres that make up Earth as a complex adaptive system.

Earth systems science is the interdisciplinary study of earth as a complex system, composed of multiple physical and biological process that interact within cycles or spheres to give rise to the overall state of the earth as an entire systems.

Of cause people have been studying earth for a long time, geologies study the formation of rocks, metrologies are interested in the atmosphere and so on,
With all of these different domains supported by the deep understanding of our physical environment that physics has built up over the past few centuries.

But it is only more recently that satellites have started to allow us to see earth as an entirety and human activity has begun to have a significant enough effect to alter earth systems making it increasingly important for us to be able to model and manage them.

From space we can view the net results of earths complex interactions and with high-tech sensors on land and in the ocean, we are getting an clear idea of its overall make up, from this researchers in different domains are discovering how their pieces of the puzzle are related to each other.

Earth systems science then tries to develop models that gives an integrated picture of how all these parts fit together, the first of these models is of earth as a systems in space with inputs and outputs of energy or radiation from the sun, with this energy being the primary factor in driving the dynamics process within the system.

As opposed to focusing on the static properties of earths individual components
Earth systems science instead takes a more dynamic view of the world, studying the ways energy and materials cycle through the different subsystems or what are called -spheres

Earths different sphere are largely defined by the different phases of mater they are composed of thus the atmosphere is composed of gasses, the hydrosphere of liquid water and the lithosphere solid minerals added to this is the biosphere
The sum of all biological material and processes.

Within each sphere a process called a cycles take place, for example in the lithosphere we have the rock cycle driven by the thermal energy within earth's interior that releases minerals through ocean ridges and volcanoes that are weathered as they cycle through earths crust and are eventual subducted returning to their origin

The hydro cycle driven by the thermal energy of the sun, cycles water between the earths surface and atmosphere through the process of evaporation, condensation and precipitation, this process helps to distribute moisture to support ecosystems at a variety of locations

The atmosphere is a layer of gases surrounding the planet that is held in place by gravity, it is the primary vehicle of temperature and climate regulation through the Cycle of carbon in and out of the atmosphere where it functions, through the green house effect to trap the suns heart.

The biosphere is the relatively thin layer of Earth's surface that supports all biological activity on earth. The biosphere is a system also characterized by the continuous cycling of matter and energy in the form of the flow of solar energy and nutrient mineral cycles.

Solar energy flows through the biosphere along a unidirectional path, as the suns energy is inputted through plant photosynthesis and process up through what are called trophic levels form primary producers to herbivores and on to predators and apex predators.

Along side the flow of energy through food webs it the cycling of mineral nutrients the core substances required for the construction of biological materials and processes, carbon, water, oxygen, nitrogen have been continuously cycled through the biosphere from one generation to the next for billions of years

These different spheres interact to create a unique state or ecosystem, an ecosystems is the combination of a community of biological organism and a particular physical environment with which they interact...
