H2O
most of the water on earth is found in these
what are oceans?
Approximately this percentage of Earth’s water is saltwater.
What is about 97%?
the biggest human use of water is for this activity
what is agriculture?
the largest ocean
what is the pacific?
any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms include drizzling, rain, sleet, snow, ice pellets, graupel and hail
what is precipitation?
These two forces drive the hydrological cycle globally.
What are solar energy (radiation) and gravity?
The average length of time water remains in a particular store is called this.
What is turnover time (or residence time)?
the supply of water to land or crops to help growth, typically by means of channels
what is irrigation?
Permeable rock layer that stores and transmits groundwater.
what are Permeable rock layer that stores and transmits groundwater. ?
this process in which forest are often harvested as a source of timber or cleared to make way for urban growth affects the hydrological cycles
what is deforestation?
When inputs equal outputs in a water system over time, it is said to be in this condition.
What is steady-state equilibrium?
Water soaking into the ground from the surface is called this.
What is infiltration?
the process of clearing land of vegetation and covering it with 'hard' or impervious surfaces can’t let water through and as a result rainwater runs off these surfaces into our waterways as polluted stormwater.
what is urbanization?
When a lake forms distinct layers due to temperature differences, preventing mixing between surface and deeper water, this condition is occurring.
What is stratification?
This ocean process removes carbon dioxide from surface waters when phytoplankton use it in photosynthesis, and carbon later sinks as organic matter.
What is the biological pump?
most of the fresh water is locked up in these
what are ice caps and glaciers?
Impermeable surfaces like concrete and asphalt increase this type of water movement after rainfall.
What is surface runoff?
a type of land degradation land in which relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities
what is desertification?
a change in ocean circulation in the pacific ocean which has global consequences
what is el nino?
This property of water allows it to absorb large amounts of heat with only a small change in temperature, helping to regulate climate.
What is high specific heat capacity?
the % of fresh water on earth
what is 2.5-2.6%
the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. This is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.
what is sublimation?
Nutrient runoff from fertilizers can cause rapid algal growth known as this process.
What is eutrophication?
this oil-rich country has the most plants to remove salt from seawater
what is saudi arabia?
This biome strongly influences the hydrological cycle because dense vegetation increases interception and high rates of this process release water vapor back into the atmosphere.
What is transpiration?
