2. Then respond with 4 facts from the article.
3. Watch the animation of cave formation. What exactly is happening?
4. Respond in your post from #2.

  1. Florida has the most sinkholes on Earth
    Geysers spout hot water
    Groundwater needs to be cleaned to be used
    Ice can form caves

  3. 1)Ground water is water found in cracks of soil.
    2)There are three main caves that are formed with water. They are: sea caves, ice caves and limestone caves.
    3)Wells are holes in the ground that are drilled down to the water table, or an aquifer.
    4)A geyser is a hot spring that erupts at regular intervals.

  5. geysers are made of hot water and steam
    sinkholes can be almost any size
    3 types of caves are sea caves ice caves and limestone caves
    aquifers are made of grave sand sandstone and fractured rock such as limestone

  6. sinkholes are the most common when the ground is weak or wet . aquifers are under ground water deposits. caves form when rivers carve rocks into the cave . stalagtites and stalagmites are most common in caves where limestone is most common

  7. kentucky and florida has the most sinkholes in the world
    we drink more than 1 billion gallons of tap water per year
    98% of the water usable by human are groundwater
    we use more than 100 gallons of water per year

  8. here are some facts,
    -Limestone caves are made of limestone eroded by groundwater
    -Sea caves are formed when waves beat against rocks,eroding them.
    -Ice caves are formed by meltwater from glaciers.
    -many Ice Caves are valled tunnels or rooms.

  10. 1) An aquifer is an area where water can easily flow through loose sediment.
    2) A material is permeable because the water can flow through them easily.
    3) Limestone caves are the most common
    4) Geysers are casued by heat and pressure pushing the groundwater and forcing it out.

    There. In MY own words (:

  11. 1) There are three different caves: ice caves, sea caves and limestone caves.
    2) Wells are holes in the ground to reach aquifers.
    3) A geyser forms from hot water in the ground that will eventually shoot out.
    4) Sinkholes can be any size.

  12. There are many different types of caves sea caves, limestone caves, and ice caves. But in all caves there is ground water that can only form in caves or small holes in the ground. There are also wells that are big drilled out holes that go down to a source of water. Also lastly there are geysers which is boiling water that is so hot that it bursts out of the geyser.

  13. It takes 1,303 gallons of water to produce a single hamburger.
    Americans use more than 1 billion gallons a day.
    Nearly 3/4 of the water that comes to homes goes down the drain.
    The average American uses about 100 gallons of water per day.

  14. Florida has the highest amount of sinkholes in the world
    Well are holes in the ground the are drilled down to the water table
    Sea, ice and limestone are three different kinds of caves
    Limestone caves are most commonly found

  15. some things i learned are...
    -Limestone caves are the most common caves found.
    -The groundwater isn't very clean so they use wells to purify them.
    -Sinkholes can become very dangerous, by the size of the holes.
    -The water gets so hot that it blows out of the earths surface and creates a geyser.

  16. geyser=geysir
    limestone and soluble rock=sinkholes
    caves and caverns=water erosion
    geysers=hot water and steam

  17. I learned that....
    * The average american uses 100 gallons of water each day
    * It takes 1,303 gallons of water to make one hamburger
    * Geysers are made of hot water and steam.
    * In December of 2005 there were about 1,00 geysers on earth!

  18. here are some of my facts,
    A geyser erupts hot water that erupts from the earths crust at regular times.
    Aquifers act as filters for groundwater.
    Groundwater is found in eroded cracks of soil.
    Groundwater when mixed with carbon turns into carbonic acid.

  19. Aquifers are areas wher water can sink into soil, sand, and rock slowley
    Groundwater is water found in cracks of soil and rock
    Wells are holes drilled into the ground
    A geyser is a hot spring

  20. 1. The main most common cave are limestone caves.
    2. Pipes and pumps are used to pull water up from the ground.
    3. A geyser is a hot spring.
    4. Sinkholes can be almost any size.

  21. I have learned that:
    *Geysers are hot springs that contain hot water and hot steam
    *Aquifers filter water when it flows through soil,rock,and sand
    *An average american will use 100 gallons of water per day
    *All Americans combined drink more than 1 billion gallons of tap water per day

  22. A sinkhole can create a hole that can be any size
    Geysers are made out of hot water and steam
    Wells are holes in the ground that are drilled down to the water table, or an aquifer
    Americans drink about more than one billion gallons of tap water per day

  23. 1. three different caves, ice caves, sea caves, limestone caves
    2. permeable means water can penetrate the rock
    3. geysers are hot water and steam.
    4.sinkholes can be any size

  24. 1. Ground water is water that is found underground in cracks of soil, sand and rock.

    2. Caves and Caverns are a big example of water erosion.

    3. Wells are holes in the ground that are drilled down to the water table, or a aquifer.

    4. A geyser is a hot spring that erupts at regular intervals.
