When scientists measure the ratio of unstable atoms to stable atoms in a sample of rock what are they trying to determine?
They are determining the age of the rocks. Radioactive elements decay over time, so the composition of a rock can indicate when that particular strata was formed.
What would you use to measure 10.5g of rock salt?
I would use a laboratory balance, or scale to measure 10.5g of rock salt.
What do you use to measure 10.5 of rock salt?
We would use MassSingle!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Describe a method that the student could use to find the volume of this rock?
You can find the volume of a small rock in no time at all. Just fill up a container that is marked by volume with water and record the volume. Then drop the small rock inside the container. Record the new volume. Find the difference between the new and old volumes. This is the volume of the small rock. You could do this in any liquid.
Why does hydrometer is used to find the density of dock?
It is not used for this.A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids, NOT rock.To measure the density of a rock you weigh a piece of it in air, then measure the volume of water it displaces in a measuring jug.Density = mass/volume.
Where do scientists get rock samples to discover earth's interior?
They recover rock samples from volcanic eruptions.
How do scientists find the absolute age of fossils and rock correlations?
Well if it was deep in the ground it was probably old.
Explain how radioactivity is used to date rock samples?
The amount of the remaining radioactive isotopes it contains.
. Describe in a few sentences how scientists use radioactivity to determine the age of a rock.?
Scientists use radioactivity to determine the age of a rock through a process called radiometric dating. They measure the amount of radioactive isotopes present in the rock and the rate at which they decay into stable isotopes. By comparing the ratio of parent isotope to daughter isotope, scientists can calculate the age of the rock based on the known half-life of the radioactive isotope.
How do you measure water absorption of rock samples?
by weighing the object firstweighing it after it has been in the waterthat is how you measure rock absortion
What can geologists learn about the interior of Earth from rock samples?
Because is gives evidence for the Scientists that want to know more about the past. :)
What technology proved continental drift?
improvements in technology like drilling for rock samples and instruments that measure magnetism of the iron in the sea floor rock
How do scientists learn about the moon?
They look up at it through telescopes, or send a robotic rover up there to dig and bring back rock samples.
What two types of evidence do scientists use to determine what is inside Earth?
Indirect evidence from Seismic Waves, and direct evidence from rock samples.
Holes drilled several kilometers into earth's crust provide direct evidence about earth's interior in the form of?
Rock Samples.
Whit what unit of measure would scientists use to measure the thickness of the rock layer created as a result of volcanic activity?
Grams
