Properties of water |
Polarity, low viscosity, high heat capacity, high surface tension, solubility,density, transmission |
|
|
Polarity |
Water has a net charge, meaning it has polarity. This allows hydrogen bonding and water to dissolve things |
|
|
High viscosity |
Water flows easily as a liquid |
|
|
High heat capacity |
Water heats up slowly compared to other materials |
|
|
High surface tension |
Water coheres itself strongly, staying together in droplets |
|
|
Solubility |
Water dissolved many things (anything with a polar region) |
|
|
Density |
Water is more dense as a liquid then as a solid, allowed ice to float on water and life to go on in cold months |
|
|
Transmission |
The property which allows light to shine through water( photosynthesis in ocean) |
|
|
How does water dissolve compounds |
Partially negative regions of water molecules (the oxygen area) attract the positive region of molecules. At the same time, partially positive regions of the water (hydrogen area) attract the negative region of some molecules, dissolving them |
|
|
Why is transmission important to earths systems |
It allows plant life to grow, which provides food and habitat for humans and animals. It also allows photosynthesis to occur, which helps regulate co2 leaves and increase O2 levels |
|
|
Why is the heat capacity of water important to earths systems |
It prevents earth from heating too quickly. It also allows atmospheric convection to occur which drives the worlds weathering events. The warmer near the equator warms air, which decreases density and caused uplifting motion. This uplifting motion is the start of conversion in a Hadley cell which drives the weather events on earth |
|
|
How is water a destructive forcs |
Chemical weathering (acid dissolution) Physical weathering (such as erosion) |
|
|
How does water create new formations |
Through deposition (physically depositing materials that were being carried in the water (suspension)) Through precipitation; minerals chemically coming out of solution and being left somewhere |
|
|
How percolation and precipitation create new formaions |
Percolation as group water sees through the soil it dissolved minerals. Eventually as they reach an opening such as a cave , they may come out of a solution as a precipitate and from solid mineral forms ions again. This can form stalgmites, stalgtites, caves, sinkholes |
|
|
What effect does water have on molten rock |
Lower the viscosity of magma |
|
|
Waters involvement in the rock cycle; water can dissolve in magma to lower the viscosity of magma, increasing the flow of magma and changing the rate of which igneous rocks form |
Waters involvement in the rock cycle; water can dissolve in magma to lower the viscosity of magma, increasing the flow of magma and changing the rate of which igneous rocks form |
|
|
Idk |
Waters involvement in the rock cycle; water can dissolve in magma to lower the viscosity of magma, increasing the flow of magma and changing the rate of which igneous rocks form. Water can chemically react with rocks to form metamorphic rock, water can also break metamorphic and igneous rock to form sedimentary |
