Pl hurry Read this excerpt from "Mars: Landscape of the Red Planet."

In addition to its volcanic landscape, Mars also has an amazing system of canyons known as the Valles Marineris. Scientist have ruled out water as the reason for the formation of these canyons. Instead, they theorize that the canyons were formed from the splitting of the Martian crust due to the cooling of the planet. Valles Marineris runs 2,500 miles long at a depth of 4 miles, dwarfing the Grand Canyon back on Earth, which is only 500 miles long and 1 mile deep.

Canyons on Mars appear to have been formed by the splitting of the Martian crust. However, canyons on Earth were most likely formed by

the impact of asteroids causing damage to the surface.
water flowing through rivers over long periods of time.
earthquakes causing parts of Earth’s crust to rise up.
the rising of hot magma from deep inside Earth’s core.

Read the excerpts from part 3 of "an occurrence at owl creek bridge." a rising sheet of water curved over him, fell down upon him, blinded him, strangled him! the cannon had taken a hand in the game. as he shook his head free from the commotion of the smitten water he heard the deflected shot humming through the air ahead, and in an instant it was cracking and smashing the branches in the forest beyond. *** a whiz and rattle of grapeshot among the branches high above his head roused him from his dream. the baffled cannoneer had fired him a random farewell. he sprang to his feet, rushed up the sloping bank, and plunged into the forest. *** as he is about to clasp her he feels a stunning blow upon the back of the neck; a blinding white light blazes all about him with a sound like the shock of a cannon—then all is darkness and silence! what function does the motif of the cannon serve throughout the story? the cannon continually pushes farquhar to continue his journey through his dream and back to reality. the cannon encourages farquhar to investigate whether his escape was a dream or reality. the cannon reminds farquhar that time is subjective and encourages him to move quickly in order to reach his home. the cannon represents farquhar’s romantic dream that he escaped his execution and will return home.
