essay and look for any corrections that she needs to make. When
you finish reading, answer the questions that follow.

(1) Humans are naturally curious beings. (2) We are driven
to search for new places to explore. (3) Given how many natural
wonders have been discovered around the world, isn’t it amazing that
there are still natural wonders to find? (4) In the year 2000, two
miners in Mexico stumbled upon one such surprise—a cave of crystals
unlike any other.

(5) Nine hundred and eighty feet below the surface of Naica,
Mexico, miners were excavating a new tunnel and found a cave filled
with giant crystals. (6) The cave is a geological wonder because it
contains some of the largest natural crystals ever discovered in the
world. (7) Scientists and explorers studying the cave named it Cave
of Crystals—for the surprises inside. (8) These crystals are Classified
as selenite crystals, meaning they are translucent. (9) Most are
between 20 and 36 feet long and weigh around 55 tons.

(10) At first, scientists wondered how the crystals grew so large
inside the cave. (11) Naica is on top of an ancient underground fault,
which is a break in the ground where the tektonic plates of Earth
have shifted. (12) Below the cave is a magma chamber filled with
lava. (13) Over time, the cave was flooded with groundwater that
trickled in from the surface. (14) With the water inside the cave and
the heat from the magma chamber, the cave remained a consistent
temperature for 500,000 years, and this created the perfect
environment to grow crystals.

(15) Scientists don’t know much about the crystals yet; the
extreme conditions inside the Cave of Crystals make it dangerous
to stay inside the cave for more than a few minutes at a time.
(16) Because the magma chamber is right below the cave, the
temperature is between 100°F and 150°F. (17) The relative humidity
inside the cave is between 90% and 100%. (18) The average
humidity in Mexico City is about 50%, making the cave’s humidity
almost double the average of the nation’s capital. (19) In order to
learn more about this impressive minerallogical discovery, scientists
exploring the caves are working to develop strategies and tools that
will help them stay underground longer.

(20) Amazing discoveries like the Cave of Crystals in Mexico
help us learn more about our world and its natural wonders.
(21) If there is a shocking cave like this 980 feet below the surface
of Mexico. (22) Then there could be more discoveries just like it in
other parts of the world. (23) There are still corners of the world that
have not been seen by human eyes, perhaps with surprises just as
dazzeling as the Cave of Crystals.
