Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanicrocks that are exposed at the Earth's surface to determine the relative agesof geological events preserved in therock record.

Answer:

Geologists use Relative Dating to determine the age of rocks through the use of fossils.

Explanation:

Relative dating relies on the study of fossils and strata to stimulate rock age. However, only fossils that are distributed in short time intervals in the history of the earth, having a wide geographical distribution, allow this dating. These fossils are called old fossils. The method of relative dating is based not only on the information provided by the fossils but also on two other fundamental principles: the principle of initial horizontality, whereby, if there is no disturbance, sedimentation takes place regularly, forming layers generally parallel and horizontal strata, and the principle of strata overlap, according to which each stratum is older than the one that covers it.

Which of the following would make the best index fossil?

Citrus2011 [14]

Answer: I would go with B. Here’s why: An index fossil is usually easily recognizable, and underwent a wide geographic distribution. What leads me to believe B is the correct answer, is because it’s something that existed “ all over the world”.

How does the closing of the stomata limit photosynthesis?

ycow [4]

Answer:

Stomata opens to intake carbon dioxide in the presence of light there by allowing the process of photosynthesis during the day time.

Explanation:

The gaurd cell of the stomata play an important role in regulating the photosynthesis. During the day time, the stomata is open which allows intake of carbon dioxide from atmosphere. Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
