3 0

Answer:

False

Explanation:

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.  Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites.  Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.

Which is the first step that geologists must do to compare rock layers at distant locations? 1.find the absolute age of rocks at
VARVARA [1.3K]

Answer:

2.compare a layer at one location to layers at other locations

Explanation:

Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
