Earth System Webquest

Ø Introduction:

What is the Earth system? A system is a group of parts that work together. Scientists have started to view Earth as a dynamic system – a combination of different parts that interact, forming a collective whole or entity. The Earth system involves a constant flow of matter through its four different parts. The Earth system is made up of four central components known as the subsystems- the hydrosphere (water), geosphere (rock), atmosphere (air), and biosphere (life). Because a major source of energy for the Earth processes is the sun, it should also be considered part of the Earth system. The two main sources of energy for the Earth system are (1) heat from sun and (2) heat flowing out of Earth as it cools.

Ø Task: At the end of this webquest, you will be presented with a photograph. You will have to choose one part of the Earth system and describe how the other parts might be affected if the first part were removed.

Ø Process: View the following videos in their entirety, then re-watch them. Pausing them when needed to complete the tables and box below. https://www.youtube.com/watch?v=VMxjzWHbyFM&t=61s

Label the parts of the following diagram:

Approximately ¾ Earth is covered by with water. Earth’s water can be solid (frozen), liquid, or a gas (vapor). It can be above ground, below ground, or in the air. Of the surface water, most is the salt water in the oceans. Only a tiny part of the hydrosphere is fresh water that is safe for humans to drink. Ø View the following video:
