  1. Aim: How do we compare the spheres of the Earth? Do Now: Earth’s Sphere’s Worksheet

  2. How do we describe the lithosphere? Solid Layer Continuous bedrock shell around the earth Most dense Solid rock material under ocean sediments Composed of Rock and Soil Lithosphere Known as the Crust Has other elements – aluminum, iron, calcium, sodium Oxygen and Silicon – 2 most abundant elements Thickness from 72 to 153 kilometers

  3. How do we describe the hydrosphere? Liquid Layer 99% salt water & 1% fresh water Oceans, lakes, rivers, streams, & groundwater Water composed of 33% oxygen and 66% hydrogen Oceans average depth of 3-5 km Hydrosphere Earth’s thinnest layer Cover’s 70% of Earth’s surface Less dense than the lithosphere

  4. How do we describe the Atmosphere? Gas Layer Troposphere contains the most mass of the atmosphere Consists of 4 layers – troposphere, stratosphere, mesosphere, and thermosphere Atmosphere (Troposphere) Troposphere- temperature decreases with increasing altitude Least dense of all the spheres We live in the troposphere layer (lowest layer) Air mixture consists of 78% Nitrogen and 21% Oxygen Troposphere - only layer that contains water vapor and weather conditions

  5. High Density Low Litho Hydro Atmosphere Draw a bar graph to show the relationship between the density of each of sphere
