Answer:
The answer is 5.1852 cm/yr
.
Explanation:
In order to calculate the full seafloor spreading rate in cm/yr, we have to first calculate the half-spreading rate which can be done by simply dividing the given distance (in cm) by time (yr); after calculating the half-spreading rate, we will double it and get the full seafloor spreading rate, thus:
Distance = 3,500 km = 3,500 × 100,000 cm = 350,000,000 cm
Time = 135,000,000 years
The half-spreading rate = distance ÷ time = 350,000,000 ÷ 135,000,000 = 2.5926 cm/yr
.
Therefore, the full seafloor spreading rate = 2.5926 cm/yr × 2 = 5.1852 cm/yr.
The Andes Mountains are shared by Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina, and Chile.

After all ice caps have melted and the polar bears drown, and the coastal cities are all underwater, Al Gore will ride a spacecraft to the Moon or Mars and inhabit there and tell everyone I told you so...
Answer:
Sample
Explanation:
Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations. A sample should represent the population as a whole and not reflect any bias toward a specific attribute.
