Earth’s SpheresBy Wylie Flint

The Lithosphere The Lithosphere is the solid outside of the

Earth The Lithosphere consist of the upper mantle

and the crust The Lithosphere is always moving in huge

chunks called plate tectonics When the plate tectonics move, it’s called

continental drift

The Lithosphere When the plates rub against each other,

they form volcanoes, and when enough pressure forms the volcanoes erupt

Scientist believe that all the continents used to be one big landmass called Pangaea, which was separated by continental drift

The Hydrosphere The Hydrosphere is all the water on and

above the Earth The water cycle is part of it, water collects

in clouds as vapor, comes down in snow or rain, collects in lakes, rivers, and oceans, evaporates and starts the cycle over again

Aquifers are underground reserves of water

The Hydrosphere Precipitation is the amount of water vapor

in the air Precipitation can make it feel hotter, like if

it’s 80 degrees out and its very humid, it might fell like 50

The Hydrosphere consist of water, ice, and water vapor in lakes, oceans, and rivers

The Atmosphere The Atmosphere is the gases outside of the

Earth The Atmosphere is made up of five layers,

the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere

The atmosphere is 78% nitrogen, 21% oxygen, and 1% water vapor

The Atmosphere

The ozone layer is located in the stratosphere

It has lots of ozone in it which protect us from the suns harmful rays

The higher you go, the less pressure there is, the lower you get, the higher the pressure

The Biosphere

The Biosphere is all of Earth The components of the biosphere are

the spheres, all living and unliving organisms, and every other thing on Earth

The food chain is the order of what gets eaten and by what

Biosphere

For instance, a tiger is a predator so it’s high up on the food chain and may get eaten only by a lion

Ecosystems are pieces of land that have certain animals and plants

There are five types of ecosystems

How the Spheres Interact The Atmosphere keeps the Biosphere,

Lithosphere, and Hydrosphere from burning up, it also gives us oxygen to breath

The Hydrosphere gives the plants and animals in the Biosphere water to drink

The Biosphere gives the Atmosphere air, and food for us to eat

The Lithosphere is the land that holds the Biosphere and Hydrosphere and gives us land to build shelter
