Spheres of The
Earth

Lithosphere







Plate tectonics, volcanism, earthquakes, continental drift.
The lithosphere is the solid, rocky crust covering the
Earth.
It covers the surface of earth from the top of Mount
Everest to the bottom of the Mariana Trench.
The lithosphere is divided into a lot of crustal plates that
is what a plate tectonic is.
The phenomena connected with volcanoes and volcanic
activity is what volcanism is.
A series of movement in the Earth’s crust is an
earthquake.
The lateral movement of continents resulting from the
motion of crustal plates is the continental drift
Hydrosphere





The water cycle, what the hydrosphere consist of ( rivers,
aquifers, and precipitation)
The hydrosphere is composed of all water on or close to
the earth.
This includes the oceans, rivers, lakes, and even the
moisture in the air.
Ninety – seven percent of the Earth’s water is in the
oceans. The hydrosphere is often called the “water sphere”
Water is found in vapor, liquid, and solid states in the
atmosphere.
Atmosphere





Relationships between pressure and height, layers of the
atmosphere, function of the atmosphere.
The atmosphere of Earth is a layer of gases covering the
core.
The atmosphere protects live on earth without an
atmosphere there would be no live on Earth.
The atmosphere is a mixture of nitrogen, oxygen, and other
gases.
The atmosphere blocks some of the sun’s dangerous rays.
The layer’s of the atmosphere
Biosphere





The part of the Earth’s crust, waters, and atmosphere that
supports life.
It includes between 3 and 30 million kinds of plants, animals,
and fungi.
The biosphere extends over the Earth’s surface in a thin
layer.
The biosphere is a life supporting global system.
The ecosystem is all living things on Earth
The Interaction


Water in the oceans today evaporates into the atmosphere
tomorrow
and falls as rain and creates puddles and lakes for all the
animals to drink
More facts on interaction of spheres



Pollution-the introduction of harmful substances or
products into the environment.
Erosion-the process by which the surface of the earth is
worn away by the action of water.
Flooding- when to much water is located in one place
