All layers are incredibly important. If we didn't, we would die very quickly and life would be inhabitable. The radiation from the son would kill us. The heat from the sun would dry up water and kill crops leaving us with no food/water.
Answer:
d
Explanation:
how much energy is coming from the star per square meter per second, as measured on Earth. The apparent brightness of a star is described by a magnitude that is a positive number for most stars, but can be a negative number for, say, Venus.
In geology, the Radioactive dating is significant because its provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
<h3>What is a Radioactive dating?</h3>
This refers to the technique that is used to know the date of materials such as rocks or carbon in which the trace radioactive impurities were selectively incorporated when they were formed.
It determines the dating of rocks and minerals through the use of a radioactive isotopes, it is also useful for igneous and metamorphic rocks that cannot be dated by the stratigraphic correlation method.
As the carbon dating helps to determine the age of an object containing organic material by using the properties of its radiocarbon, it is considered a poor tool for finding the age of the dinosaur skull in the purple layer because the collagen in the dinosaur's bone has usually long since decayed away and is therefore unavailable for radiocarbon dating.

Abundant moisture and warm temperatures result in high rates of chemical weathering.
Chemical weathering is due to rainwater reacting with the mineral grains in rocks to shape new minerals (clays) and soluble salts. these reactions arise especially while the water is slightly acidic.
Weathering breaks matter down into smaller portions. The motion of pieces of rock or soil to new places is known as erosion. Weathering and erosion can cause adjustments to the form, length, and texture of different landforms (together with mountains, riverbeds, seashores, and so forth).
The most important element of weathering is its role in the formation of soil. with out soil, existence, as we realize it on the earth, might not exist. Soil is a miles unnoticed element of earth's strategies and, at contemporary rates of human use and abuse, is becoming a finite useful resource.
