Hard definitions
This sub-sphere of the Hydrosphere specifically contains all of Earth's frozen water, including glaciers, ice caps, and sea ice.
What is the Cryosphere?
Water vapor floating invisibly inside a cumulus cloud belongs to this primary sphere.
What is the Hydrosphere?
When a volcanic eruption blasts sulfur dioxide gas and ash high into the sky, blocking incoming solar radiation, it is a direct interaction between the Geosphere and this second sphere.
What is the Atmosphere?
THis gas makes up roughly 78% of the dry air in Earth's Atmosphere, far outweighing the oxygen we breathe.
What is Nitrogen?
Unlike the rest of the Geosphere which is rocky and solid, this specific underground molten layer provides the raw materials for Igneous rocks when it erupts.
What is magma (or the mantle)?
Decaying bacteria and fungi breaking down a fallen log on the forest floor belong to this sphere?
What is Biosphere?
Heavy rainstorms cause a mudslide down a steep mountain cliff. Name the two primary spheres interacting to reshape the land.
What are the Hydrosphere and Geosphere?
Coal, oil, and natural gas (fossil fuels) originated from ancient plants and animals trapped and pressurized inside the Earth ove rmillions of years, linking the Biosphere to this other major sphere.
What is the Geosphere (crust) ?
What is the greek word for life?
What is Bio?
Name a part of the Atmosphere.
What is the Thermosphere, Mesosphere, Stratosphere, ozone layer, or Troposphere?
Plants pull carbon dioxide out of the air and release oxygen via photosynthesis. This fundamental chemical process links the Atmosphere, the Biosphere, and this third foundational sphere.
What is the Hydrosphere (water is required for photosynthesis) ?
This primary external energy source drives the circulation, evaporation, and movement in both the Atmosphere and the Hydsrosphere.
What is the Sun?
This is the specific boundary of combined layer made up of the crust and the very top solid part of the upper mantle?
What is the Lithosphere?
Coral reefs- built out of calcium carbonate skeletons secreted by tiny marine animals - represent a structural cross-section of these two specific interacting spheres.
What are the Biosphere and Hydrosphere (or Geosphere) ?
Melting polar ice caps reduce the Earth's surface reflectivity, causing the oceans to absorb more thermal energy and warm up. This triggers a complex feedback loop between the Cryosphere, Hydrosphere, and this third sphere.
What is the Atmosphere?
This process by which liquid water changes to gas through microscopic pores in plant leaves adds moisture directly to the air, creating a vital bridge between the Biosphere, Hydrosphere, and Atmosphere called this.
What is Transpiration?
