Answer:
The grain size
Explanation:
The grain size can provide lot of clues for us when it comes to the formation of the rocks, the conditions in which they formed, and even what happened after their initial formation. The reason for this is that the grains vary in size and shape depending on the conditions in which the rocks formed. If the magma/lava cooled of quickly, the grains will be very small, almost unnoticeable, and that is a sign that the cooling appeared on the surface, very close to it, or in the presence of water. On the other hand, if the magma cooled slowly, the grains will be large and well defined, and that is a sign that the magma was cooling off slowly, deep into the crust, where there's higher temperature and pressure.
The answer is D, hope this helps.
<em>Answer:-</em>
<em>Working slowly over many years, ground water travels along small cracks. The water dissolves and carries away the solid rock gradually enlarging the cracks, eventually forming a cave. Ground water carries the dissolved minerals in solution. The minerals may then be deposited, for example, as stalagmites or stalactites.</em>

Answer:
A mid-ocean ridge
Explanation:
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
Answer:
a. Transversal r
b. Transversal q
c. Transversal s
d. Transversal q
e. Transversal p
Explanation:
Recall: A transversal is a straight line that cuts across two straight lines.
a. Transversal connecting <1 and <5 = transversal r (this cuts across lines p and q)
b. Transversal connecting <7 and <14 = transversal q (this cuts across lines r and s)
c. Transversal connecting <8 and <11 = transversal s (this cuts across lines p and q)
d. Transversal connecting <6 and <15 = transversal q (this cuts across lines r and s)
e. Transversal connecting <3 and <9 = transversal p (this cuts across lines r and s)
