We continue our study of the changing surface of the earth by looking at glaciers. We will look at glaciers in Alaska and Greenland.

We will describe what a landslide looks like and possible causes. We will view videos of landslides and the changes they make on the earth's surface.

We discussed earthquake magnitudes, locations, frequency, and predictability.

We will look at examples of how erupting volcanoes change the earth's surface. We will discuss the reason for volcanoes to erupt.

We discussed wind erosion and observed pictures of rock formations caused by wind erosion. We also looked at beach erosion caused by waves and by wind. We discussed methods to prevent erosion.

We will discuss the effect of water on land and soil that results in erosion.

We looked at pictures of several canyons. Each had a river running through it leaving behind a walled canyon. We discussed how the river shaped the canyon.

We will discuss materials that are renewable such as paper (from wood), solar power, wind power and food products. We will compare them with materials that are not renewable such as oil.

View 2 videos which describe and define electromagnetism and electromagnets.

We will discuss the process of recycling various common items. We will also talk about recycling specific items such as electronics and metals.
