There are no passengers on spaceship earth.
We are all crew. Marshall McLuhan

We live on the earth. The earth is ‘our shelter’. The land was once one large land mass called Pangaea. Because of continental drift and plate tectonics, we now live on seven continents and travel the five oceans. Check out this Plate Tectonics Pop-Up Book to see how the earth’s surface is constantly in motion. We live on mountaintops, in the plains, in the valleys, and on peninsulas and islands. We are able to live on the earth because of our atmosphere and the topsoil underneath. Between these two layers, everything we need to live is provided. Almost 8000 miles in diameter, the earth rotates about its axis, which is tilted at 23.5 degrees and takes approximately 365 days, or one year, to revolve around the sun. The earth receives the sun’s radiation at different angles, and higher and lower levels create the seasons.

Enjoy this life on the earth. Tread on her gently!

Activity 1 – Diagram A Section Through The Earth!

Backgrounds 1423861910 earth activity 01

Our earth is in a solar system. The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers) or app. 8,000 miles. It turns out that the earth is not a prefect sphere but is actually only 7,901 miles (12,715.43 km) when measured through the poles, making it wider than it is tall, with a slight bulge at the equator. The earth’s shape is known as an ellipsoid or geoid.

First, calculate the difference in the earth’s diameter at the equator and at the poles. Next, calculate how deep you would have to drill to get to the center of the earth. Next draw a section through the layers of the earth and label it.

Print a map of the earth (Insert link to printable world map): find the seven continents and the five oceans. Color in the continents making the desert areas yellow, mountain ranges grey and the rest shades of green. Color the oceans and seas blue. Label Africa, Antarctica, Asia, Australia, Europe, North America, and South America. Next label the major oceans and seas.

Activity 3 – Track An Explorer's Route

Backgrounds 1423861928 earth activity 03

In the history of the world, there have been many great explorers who have bravely gone off on journeys to unknown destinations. From the Americas to the South Pole, people have dared to face the challenges of weather and geography to map the ‘corners’ of the earth. Pick an explorer from the website and research his or her path and mode of travel. Map the path on a world map, locating key stops, dates, and discoveries.

If you could explore, where would you go?
