temperature
pressure
evaporation
salinity
none

Which of the following is an example of positive feedback in an earths system
exercise makes a person warm they perspire which cools their body

a field of grass absorbs sunlight , grows tall, produces seeds, and releases the seeds to produce a new generation of grass
warm air melts sea ice exposing more seawater to sunlight which warms the water the warm water is harder to freeze when they are temperature drops

about five hundred thirty million years ago land that would later become Florida formed through volcanic activity in the buildup of sediment over hundreds of millions of years has repeatedly Summers as glaciers melted and the sea level Rose then they got to expose as temperature cooled and Glaciers reform. Which spheres interacted most to make land that is now Florida?
geosphere, hydrosphere, cryosphere, biosphere
geosphere, hydrosphere, cryosphere

the pollution would be cleaned up before I could threaten any other state
no the lakes have no drains so the pollution would stay put
none
- 10. Poll

increase the amount of liquid surface water including the volume of oceans
increase the total amount of water in the hydrosphere
drain ground water from the world's aquifers
