Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves

Answer:

The correct answer is limestone.

Explanation:

A cave is the product of undone limestone.

This stone is weakened by the rain and carbon dioxide that is absorbed by the soil, this causes the stone to fracture, sometimes enough to form a cave.

Where there is more water flow, the bigger the cave will be.

What is necessary for a cave to form is a stone that can be diluted with water.

Because of gravity, water will always want to go down, this is what will cause the rock to dissolve forming different types of caves.

If you dribble a basketball with a frequency of 1.77 Hz, how long does it take for you to complete 12 dribbles?
Licemer1 [7]
<h2>It takes 6.78 seconds to complete 12 dribbles.</h2>

Explanation:

Frequency of dribble = 1.77 Hz

That is

         Number of dribbles in 1 second = 1.77

         \texttt{Time taken for 1 dribble = }\frac{1}{1.77}=0.565s

Now we need to find how long does it take for you to complete 12 dribbles.

         Time taken for 12 dribbles = 12 x Time taken for 1 dribble

         Time taken for 12 dribbles = 12 x 0.565

         Time taken for 12 dribbles = 6.78 seconds      

It takes 6.78 seconds to complete 12 dribbles.
