Answer:
Limestone.
When carbonic acid seeps through limestone underground, it can open up huge cracks or hollow out vast networks of caves.
Explanation:
This is the process of chemical weathering.
This is the chemical reaction between Carbonic acid (H2CO3), i.e. Acid Rain, and the Limestone (CaCO3), i.e. Calcite. The product of this reaction is Calcium Bicarbonate Ca(HCO3)2, which is soluble and is washed away by the rain.

Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
Longshore current move parallel to the shore as longshore drift under the prevailing wind in zig-zag motion.
It is an ocean current that is cause by swell sweeping into the shoreline at an angle and pushing water down the length of beach in a uniform direction.
It is a geological also process that consist of the transportation of sediments such as silt,clay,sand and shingle.
