    How dose a sinke hole happen? A sinke hole can happen if there’s a lot of water around and it will start to sinke slowly as it pulls every thing in around it. I think it can also happen by an earthquake making the ground shake and make a sinke hole.

    I think the builders are trying to rebuild the house and also there’s a sinkhole in the ground and also where the workers are near the edge of the cliff where the sinkhole there is a pond and one of the workers might end up falling into the pond.

    First the limestone level starts to desolve and then falls in on itself.
    Then that leaves the clay unsupported and it falls in on itself and creates a sinkhole

    1.the water has made a fair way down.
    2.it started to make a wide hole only so you can see the dirt.

    It rains and the rain soaks through the ground and makes a puddle under the ground.
    The dirt sinks down into the empty hole and fills in the hole then later the hole gets bigger.

    As the limestone starts to disappear the crakes get bigger and it carries more water in it. Sinkholes are formed when the land above collapses onto its self and makes a sinkhole.

    A sinkhole is also formed when there are vibrations from new constructions, pressure form standing water, sands and clay.

    1. When limestone under the water starts to dissolves there is a big space left and it can’t hold it’s self so it collapses.
    2. Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the hole.
    3. When the acidic water moves through spaces and cracks underground, it slowly dissolves limestone and creates a network of large cavities and holes.
    4. Sinkholes can also occur when people over withdrawal the water out from under houses,roads and oceans.
    5. it can also occur when people drill new water wells and when weight is put on top it can’t hold itself and it collapses.
    6. it can occur when the water source finds new cracks underground escaping and leaving an empty cave.

    the limestone gets wet then it it brings the earth together than it forms a big hole in the
    ground or the water . it makes a cave in the ground. It leaves the clay unstably
