DIFFERENCES BETWEEN VIRUS AND BACTERIA
Are they living things? Where can you find them?
LEVELS OF ORGANIZATION
All living things (organisms) are organized. This means they are specially designed to perform different life functions. The smallest level of organization of living things is a cell. Cells are the smallest unit of life.
THE CELL
All living organisms on Earth are divided in pieces called cells.
EVOLUTION
Where do we come from?
EROSION
We have learned about how landforms are created. Mountains, and valleys
form as tectonic plates crash into one another. These mountains do not
last forever. They are torn down by erosion.
EARTHQUAKES
Cool Earthquake fact: the interior of Antarctica has icequakes which are perhaps more frequent than earthquakes in Antarctica. The icequakes are similar to earthquakes, but occur within the ice sheet itself instead of the land underneath the ice.
VOLCANOES
Where can
you find most of the volcanoes?

EARTH´S ATMOSPHERE
To understand the Earth´s relief you better know first how the Earth´s crust is formed.
TYPES OF ROCKS
By looking at sedimentary rocks of different ages, scientists can figure out how climate and environments have changed through Earth’s history. Fossils of ancient living things are preserved in sedimentary rocks too.

EARTH´S ATMOSPHERE
Without the atmosphere, we will not be able to live on Earth. The gases
in the atmosphere protect us by blocking out dangerous rays from sun and
making Earth a perfect habitat for plants and animals. Let's find out
what are those gases which supports life on Earth.
