I think both options are true!
One of the most common forms of weathering in areas that have frequent freeze/thaw cycles is ice wedging.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
Answer:
hmm its true because if we clean up after ourselves and get the trash out of the ocean and everywhere else it would pretty much help. :D
Explanation:
Answer:
tensional
Explanation:
Tensional stress, meaning rocks pulling apart from each other, creates a normal fault.
