Ionosphere
troposphere
thermosphere
Most weather occurs in the troposphere which is closer to the earth. Option C
The troposphere is the lowest part of the atmosphere, rising from the surface of the planet to an average height of between 5 and 9 miles (8 to 15 kilometers), depending on the location. The majority of meteorological phenomena, including clouds, precipitation, storms, and winds, occur at this layer.
The temperature gradient, or drop in temperature with altitude, is a key feature of the troposphere. Convection and vertical air movements caused by this temperature gradient are what cause clouds and precipitation to form. Weather patterns and atmospheric disturbances are created by the interactions of air masses with various pressures and temperatures throughout the troposphere.

Answer:
Steroids belongs to the group of lipids. This a biologically active substance(organic molecule) which has four rings arranged in a specific molecular configuration.
They are chemically lipids because they are insoluble in water because they are hydrophobic.
Cholesterol is the most common kind of steroid which is known to be the precursor to vitamin D.
B) identifying the minerals within it.
C) studying how it has been affected by erosion.
D) comparing the size of one layer with other layers.
Answer; Radiometric dating
Explanation:How do scientists determine the ages of the rock layers?
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer.
