The Geosphere is associated with solid portions of the Earth. It includes the continental and oceanic crust and all other layers of the Earth's interior.  This includes all rocks, sediments and soils, surface landforms and the processes that shape the Earth's surface.

This sphere is the outer part of the Earth System that extends nearly 500 km above Earth's surface and includes an ever-changing mixture of gas and small particles surrounding the Earth’s surface.

Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.

The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rain forest is a dense green mass of humid jungle that covers northeast South America.

NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or

Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make an images which allow us to see patterns more easily. Students will make a false color image using a set of numbers.

Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.

Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless.

Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). As can be seen through a prism, many different wavelengths make up the spectrum of sunlight. When sunlight shines on objects, certain wavelengths are absorbed and other wavelengths are reflected.

Helping students build their understanding of Earth's spheres and how they are connected is difficult.  Review the graphics below to help identify the parts of the Earth System and the processes that connect them at the local, regional, and global scales.
