Earth’s Spheres
• Atmosphere: located right above the Earth’s
surface and includes layers of gases (clouds, air
pollution, sand storms, hurricanes, etc.)
It protects us by absorbing solar radiation.
• Biosphere: life on land, rivers and oceans
(Biomes) deserts, forests, grasslands
• Hydrosphere: water in liquid and solid state
(oceans, glaciers, snow, lakes, rivers, etc.)
• Lithosphere: solids of the Earth (rocks, soils,
landforms, etc.)

Types of Boundaries
A DIVERGENTboundary is a boundary where two
tectonic plates are moving away from one
another. This most often takes place at ocean
ridges.
A CONVERGENT boundary is when plate
tectonics, push against each other, one is
ultimately forced down beneath the other.

Boundaries continued
• TRANSFORM is the final type of boundary. The
two plates slide against each other in a
sideways motion.
