water is the fundamental ingredient for life looking at our Earth from space with its vast and deep ocean it appears as though there is an abundance of water for are you however only a small portion of Earth's water is accessible for Arnie's how much fresh water exists and where it is affects us all  nearly two-thirds of this fresh water is stored in the polar ice caps snow packs and Glaciers make inaccessible for long periods of time the water cycle is dynamic it describes the continuous movement of water on above and below the surface of the Earth and the transitions from one state to another sea surface temperature surface winds and air temperature influence the rate of evaporation at the ocean surface  in the tropics warm ocean surface temperature support High rates of evaporation when also increases evaporation when the air temperature is warmer it can hold more well the atmosphere not store a large quantity of water compared to the ocean rivers and lakes it can transport water quickly from one place to another lowline regions of the atmosphere with high moisture and strong winds can form atmospheric to transport water horizontally clouds are formed as water vapor cools and condenses droplets and ice crystals  clouds and water vapor act as insulators in the atmosphere  clouds help Shield the Earth from fun and trap heat from Below when Cloud particles grow large enough they may fall out as rain or snow under the right conditions areas of precipitation can grow into large storms  as storms grow they transfer heat quickly into the upper atmosphere the migration of storms helps to distribute heat between the Equator and poles shaping wind patterns globe how storms growing intensify depends on atmospheric moisture surface temperatures and wind patterns precipitation is concentrated in some parts of the world and scares in others it can vary substantially from season to season and from you 2 year what are the falls on the land surface is precipitation is stored within snowpacks Lakes reservoirs oils and underground aquifers  what are availability varies from place to place and over time  the availability of water affects the type and abundance of vegetation the primary so food for animals and people  extreme water cycle variability unusually dry or wet conditions impacts humans worldwide each year hazards such as floods exact up costly economic and human most of the water that falls on the land remains stored there for weeks or more snowfall is stored as snow pack or ice meltwater in rainfall are stored in lakes and soils some of the water is absorbed by plant roots or drains into the water table eventually the water will evaporate to the atmosphere or return to the ocean and streams and rivers provide a source of nutrient-rich water that supports ocean life sensors on a suite of NASA satellites observe and measure we're on land in the ocean and in the atmosphere  these measurements are important to understanding the availability and distribution of Earth water which is both vital to life and vulnerable to the impacts of climate change and the growing world population
