Earth's Spheres
This sphere includes all living things on Earth.
What is the biosphere?
The process where liquid water changes into water vapor.
What is evaporation?
Carbon in the atmosphere is mainly found in this form.
What is Carbon Dioxide?
A feedback that counteracts change and keeps systems stable.
What is a negative feedback?
Someone who studies fossils.
What is a paleontologist?
The solid, rocky part of Earth that includes the crust and upper mantle.
What is the geosphere?
When water vapor cools and forms clouds, this process occurs.
What is condensation?
Plants remove carbon dioxide from the air through this process.
What is photosynthesis?
A feedback that amplifies change and makes systems more unstable.
What is a positive feedback?
Someone who studies all things space.
What is an astronomer?
This sphere contains all of Earth’s water, including ice, rivers, and groundwater.
What is the hydrosphere?
Precipitation that soaks into the ground and becomes groundwater.
What is infiltration
Plants and animals break down and release stored carbon
What is decomposition?
Melting ice exposes darker ocean water that absorbs more heat. This is an example of what type of feedback?
What is a positive feedback?
Someone who studies ocean life.
What is a marine biologist?
When volcanoes release gases into the air, it’s an interaction between these two spheres.
What is the atmosphere and the geosphere?
provides all the energy for this cycle
What is the Sun?
a storage of carbon atoms
What is a reservior?
Increased cloud cover from more evaporation can reflect sunlight and cool Earth , this is what type of feedback?
What is a negative feedback?
Someone who studies reptiles.
What is the hydrosphere and biosphere/geosphere?
Explain one way that the biosphere interacts with the geosphere.
...
The movement of water through plants and its release as vapor.
What is evapotranspiration?
When animals die, carbon can become stored in these long-term reservoirs over millions of years.
What are fossil fuels or rocks?
Describe one feedback loop related to carbon and global temperature.
...
Someone who studies life in space.
What is an astrobiologist?
