Many hazards can be hiding in standing water. One of the most treacherous is sinkholes. Another danger in many states is flash floods. Even six inches of water can be hiding a current that will sweep your car away. (If your doing your your driving permit your answer should be "All of the above".)
subsidence sinkholes are different from collapse sinkholes in two ways . first,subsidence sinkholes ocer when there is almost no overburn,or material,above the limestone. collapse sinkholes happen when there is thick overburn. secondly, subsidence sinkholes occur slowly, over time, while collapse foms quckly beacause of human activity , such as well drilling.
Cold currents remove thermal energy from the air above and warm currents warm the air above Apex
It is from differing temperatures of air above it that causes currents to flow in the water.
There are a few different ways that sinkholes can form. Often, there is a layer of limestone or some other layer of water soluble material under the ground, and it is slowly dissolved by water seeping down from above. This leaves a gap and these gaps sometimes collapse.
Sinkholes often occur when underground rivers erode the rock beneath the Earth's surface. Eventually, the land above is no longer sufficiently supported and collapses into the cave that has developed beneath it. They are more common in places with limestone, as it is easily eroded.
a.) Sinkholes b.) sinking streams c.) caverns d.) all of the above
Land is above the waterline. No surface currents can flow over land.
Above limestone deposits
currents rise and then go down ,which it in cycle to add on to the above; the currents move clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
