The correct answer is False. Planets travel on their elliptical orbits. They move faster when they are closer to the sun. The presence of external gravitational forces and elliptical orbit will never give them a constant rate.
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.
Answer:
Sampling
Explanation:
Sampling is a statistical procedure in which a selected number of observations is used to represent the whole observation. When we take an area and we use the population to estimate that of other areas or the whole population, we are simply sampling. Sampling is very important to some specific forms of observations. Sampling can be done randomly or in a systematic way. The goal of sampling is using the part to represent the whole.
Hello, the answer to this is True.
Thank you.
Answer:
Kelvin wave
Explanation:
The Kelvin waves are usually defined as one type of planetary waves that are characterized by the presence of large peaks as well as valleys that can eventually lead to the change in the depth of ocean water. These are non-break waves.
This type of wave occurs during the time of occurrence of El Nino, which flows only towards the eastern side covering the equatorial region. These are large waves extending up to thousands of miles.
This wave occurring in the equatorial region normally has two phases, namely the up-welling phase, and the down-welling phase, and this eventually leads to various changes in the surface temperature of the sea as well as in the subsurface region within the eastern part of tropical Pacific ocean.
