What indicates a certain body of rock of a specific age?
The fossils found in the rock layers indicate the age of the rock. By studying the index fossils and comparing them to known age ranges, geologists can determine the age of the rock layer. Other methods such as radiometric dating can also be used to determine the absolute age of the rock.
Can texture provide clues as to how and where a rock was formed?
A rock's texture will most definitely yield clues as to how a rock formed and often to where it formed. Coarse grained igneous rocks formed below the surface from magma. Fine grained igneous rocks formed at or near the surface from lava. Large crystals scattered among fine grained rock indicates an igneous rock that may have partly formed underground, and finished forming above ground. Layers can indicate rocks that are sedimentary and the grain size can indicate the source of the sediments. Banded and foliated rocks indicate high pressure formation and metamorphosis, and the coarse recrystallization of quartz in quartzite indicates a high temperature metamorphosis. These are just a few examples. For information on different rock textures, click on the link below.
What does the color of soil tell us about the soil?
The color of soil can provide clues about its composition and fertility. Dark-colored soil generally indicates the presence of organic matter and nutrients, making it more fertile. Lighter-colored soil may suggest lower levels of organic matter and nutrients. Additionally, certain colors, such as red or yellow, can indicate the presence of minerals like iron or aluminum.

What can be inferred about the motion of object in terms of how far they travel in a certain amount of time?
The distance an object travels in a certain amount of time can provide information about its speed. A greater distance covered in the same time period indicates higher speed, while a lesser distance indicates slower speed. Additionally, the consistency of the distance covered over time can indicate whether the object's motion is uniform or variable.
What is the term associating different colors of feces?
There are different colors of feces for many different reasons. Black feces indicates blood and you should see a doctor immediately. Green feces may indicate that you are a certain food dye.

How stationary waves are formed?
Stationary waves are formed when two waves of equal amplitude and frequency traveling in opposite directions interfere with each other. This causes certain points, called nodes and anti-nodes, to appear stationary while other points continue to vibrate. The interference pattern creates a standing wave pattern that appears to be stationary.
