What characteristics do geologists look for when observing a rock sample?

They look at the texture of the sample (coarse or fine graining, foliation), the degree of weathering, for the presence of fossils, for stratification, reaction to acid, and the color, for a quick identification. Closer examinations at the lab will reveal the specific mineral makeup of the rock, the source of the materials from which it was formed, and additional tests could in some circumstances even reveal its age.

Name three ways geologists study a rock sample?
geologists can study a rock sample by observing its composition, color, and texture. they also look at the rocks structure, hardness and weight.
What do geologists look for?
Geologist look for rocks that have been in the earth.Geo in in geologist means earth.Geologist also may look for fossils from dinosaurs millions of years ago.
How do geologists estimate the age of mountains?
First: geologists look at the general shape of the mountain: Sharper peaked mountains are generally younger than rounded ones because erosion has had less time to wear them down (ie the Rockies are younger than the Appalachians). Second: geologists look at what type of rock is exposed. Not only does this tell us something about when the formation began, it also gives us something to base our erosion estimation off of. Sandstone erodes faster than granite, so you could have a rounded mountain peak made of sandstone that was the same age as a sharp granite peak. Third: geologists will consult with paleontologists and archaeologists to try to determine the age of the mountain based off of remains that may be present on the mountain. (If, for instance, we find fossil sea-shells, we know that the mountain formation has to fall within certain ranges).

B
If you wanted to find a sample of fermium which has an atomic number 100 were would you look?
Fermium exists in rare radiochemical laboratories and is prepared by the irradiation of curium.

What is observing science?
to take a look at it
When should you use objective lens?
A sample should be examined with low power first when observing any sample for the first time under the microscope. Now if you want to focus on one particular region in the sample then you can step it up to high power lens. Objective lens are not that expensive and good way to look at some simple tissue structures.
What does a sample private loan agreement look like?

What features do geologists look for when they prospect for ores?
Geologists prospect ores by looking at their shape, size, color and how hard it is. They also need to find what is inside the ore or else they will not know what kind of ore it is.
What does the interior of the planet mercury look like?
Based on observing Mercury and comparing Mercury with Earth, it is inferred that Mercury has a large core that is rich in iron. Planetary geologists estimate that the core of Mercury is about 42% of the planet's total volume. Data from research performed by these geologists strongly suggests that the planet has a molten core. Mercury's core has a higher iron content than the core of any other major planet in the solar system.
What does a Sample of a letter with enumeration look like?
sample of letter with enumeration
How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
What involve observing?
Observing involves you to see the changes or responds the living things or cells given to you, you'll have to look closely and classify what you saw.
What another word for look for?
