Answer:

While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake. The two scales have different applications and measurement techniques.

Explanation:

Mercalli Scale Richter Scale

Measures The effects caused by an earthquake The energy released by an earthquake

Measuring Tool Observation Seismograph

Calculation Quantified from observation of the effects on earth’s surface, humans, objects and man-made structures Base-10 logarithmic scale obtained by calculating logarithm of the amplitude of waves.

Scale I (not felt) to XII (total destruction) From 2.0 to 10.0+ (never recorded). A 3.0 earthquake is 10 times stronger than a 2.0 earthquake.

Consistency Varies depending on distance from epicenter Varies at different distances from the epicenter, but one value is given for the earthquake as a whole.

Answer:

Cypress Hills of southwestern Saskatchewan and southeastern Alberta

the Rocky Mountains are younger than the Appalachian Mountains. The Appalachian Mountains are in the East and the Rocky Mountains are in the West. ... The Coast Ranges are low mountains near the ocean and Sierra Nevada is high and covered in snow.

Its location on the west coast of a continent in the midlatitudes places the climate in the path of the Westerlies. In this situation, the climate receives a constant influx of oceanic air throughout the year. The mild temperatures are a direct result of the moderating influence of ocean bodies on air temperatures.

Mediterranean climates cover a very restricted area of the planet's total land surface, mostly found between 30 and 45 degrees of latitude. ... Humid subtropical climates prevail over a larger area, mostly between 20 and 35 degrees of latitude but extending equatorward to about 15 degrees and poleward to about 40 degrees.
