Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.
Answer:Thus we can conclude that these charcoal fragments are about 11460 years old.
Explanation:
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process = 25
b) for completion of 75 % of reaction
Thus we can conclude that these charcoal fragments are about 11460 years old.
False, there are actually around 30 different types of freshwater sponges in North America alone
I think the answer is B because it happens slowly and through natural selection
