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
- 23.32°
- x=4637.16 feet
- y=1999.8 feet
- Explanation
Sketch a triangle ABC, where A is at the apex(top) and BC is the base.Let side AB=5050 feet and BC=6000feet.Drop a perpendicular line from A to BC at O to represent distance y and OB is distance x.
Point A = your location
Point B=First tower and Point C is the second tower.
To calculate the angle in degrees we use law of cosines,
2420²=5050²+6000²-(2)(5050)(6000)(cosB)
B=23.32° is the angle in question
Secondly, we find value of x
CosB=x/5050
X=4637.16feet, the position east of the tower
Thirdly, we calculate y
SinB=y/5050
0.39599=y/5050
y=1999.77
y=1999.8 feet , the position north of the tower
The correct answer is B: rugged landscape of mountainous land. The terraces are made so that erosion and surface runoff is reduced and the water that would be lost to surface runoff is properly utilized by the plants.
<u>Answer:</u>
The statement 'south of London' is an example of 'absolute location' is false.
<u>Explanation:</u>
- A location can be said to be an absolute location when it is defined with exact longitudinal and latitudinal coordinates.
- For instance, the Royal Observatory in Greenwich, London can be said to be an example of 'absolute location' because its location can be pinpointed with the help of longitudes and latitudes.
- When we say south of London, it can be the entire area that falls south of London, which cannot be an example of an 'absolute location'.
In architecture, form refers to the shape or configuration of a building.
