A geologist examines a rock outcrop, which is an area where horizontal layers of sediment from deep within Earth have been exposed. She notices that one layer contains materials that look like they belong near water. This layer contains smooth rocks and bits of sand that look like they were worn down over time. How could the geologist use this information to determine the age and environment of the rock
Answer:
by recognizing that the layers below it are older and that the layers above it are younger
Explanation:
A geologist determining the age of the rock can use the law of superposition for estimating the age of the rock. The law of superposition is fundamental in interpreting the age of the earth as it provides the relative age of any rock layers at any location.
In the context, the geologist can identify and determine the environment and the age of the rock layer by recognizing the layers below it are older rocks and the layers above it are younger using the law of superposition.
Answer:
by reconginixziong that the layers areound above and under it are younger/older
Explanation:
young layerse are found at the top of the layers
older layers will be at the bottom

Explanation:
Given the effects of precession, will this still be the case in 13,000 years? Explain your answer. Draw a diagram to illustrate this process.
Answer:
It change the longitude of stars.
Explanation:
Precession allows the stars to change slightly their longitude each year, so the sidereal year which is the orbital period of the earth around the sun, that takes the stars as a reference frame. It is 20 minutes longer than the solar year because of precession. This motion of the Earth's axis goes backward and forward in every 13,000 years so we can conclude that there is a great effect of precession on our earth's motion.
what do you think is the reference point for earth rotation
Answer:
North Pole
Explanation:
As viewed from the north pole star Polaris, Earth turns counterclockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where Earth's axis of rotation meets its surface. This point is distinct from Earth's North Magnetic Pole.
All of the regions of the surface and atmosphere of Earth that are occupied
by living organisms is called the:
A. biology
B. biodiversity
C. biome.
D. biosphere.

Answer:
The correct answer is A.Explanation:
Becuase there was always a large labor force for the agricultural industry so this has not been a major development over the past 50 years.What materials absorb the most solar energy?(Sand, Water, Oil)
Answer:
sun,dark surfaces, water and metal.
Explanation:
Materials that absorb sunlight well include dark surfaces, water and metal. The sun's light energy arrives as a mixture of visible light, ultraviolet and infrared; some materials absorb all these wavelengths well, while others are better suited to a certain restricted types of light.

What is survey?A survey is referring as a method of data collection in which some set of questions is asked of selected individuals or samples and take their response which is utilized in research to develop new theories.
Graphic links between two sets of offering options are shown by two-way frequency tables. The amount or frequency of observations for two variables is shown in a statistical table known as a two-way or interdependence table.
