2A Biosphere
Atmosphere, hydrosphere, & lithosphere.
In this guide we examine how specific parts of the biosphere relate to life on Earth.
Video Overview
We will begin with this guide overview video.

Biosphere Guide Contents
Complete all four of these sections before taking the quiz and making your media piece.
Biosphere Objectives
Atmosphere
Describe the basic composition of Earth’s atmosphere, including how atmospheric gases relate to ozone depletion and acid rain; explain the greenhouse effect including how it relates to Earth’s climate; and provide examples of how light and color relate to leaf appearance and function.
Hydrosphere
Describe what a biogeochemical cycle is, providing examples of these nutrient cycles including sinks and the role of organisms; list key properties of the water molecule that make it significant for life as we know it; and describe ways water relates to the structures and distribution of plants.
Lithosphere
Explain the significance of bacteria in the nitrogen cycle; describe impacts on terrestrial ecosystems, including wind and soil erosion; and outline the key components of a field kit including why they are important.
Climate & Biomes
Explain how sunlight distribution leads to varied ecosystems at different latitudes; describe the impact of altitude and north vs. south-facing slopes on mountain habitats; and outline a climate and ecosystem tour from Newport on the Oregon Coast, over the Coastal Range, through the valley, over the Cascades Mountains, and into Eastern Oregon, including rainshadows along the route.
