Explanation: GPS which is an acronym for Global Positioning System is a global satellite based location and navigation system owned by the US Government. It was first used by the US Air Force in 1978. It's main purpose is to show a GPS user location and time information from anywhere on earth, where there is an unobstructed line of sight from the precise location to 4 or more GPS satellites. GPS is commonly used on land (obviously through every day use like when you use an uber) and in the air (pilots use GPS signals when they fly).
GPS can be used to track pets if there's a tracking device on their collars.
GPS is also used in taxis and can be used to track a cab after a hurricane.
Ordinary people can use GPS to collect information for scientists - an example of this would be taking a new undefined route on Google maps therefore adding to their archive of known routes/areas.
However GPS signals cannot penetrate water - sea water especially. Hence the answer is B
Answer:
It is asking what type of environment was the rock formed in. For example, metamorphic rock and sedimentary rocks are formed at different levels of temperature and pressure. To solve the problem start off with trying to identify the type of rock (igneous,metamorphic, sedimentary,etc.) and then figure out what conditions those rocks form in. I hope this helps! Good luck!
Answer:
1/3 gallon
Explanation:
Gallon of honey remaining = 3/4 gallons
Gallon of honey needed for bread = 1/6
Gallon of honey needed for cookies = 1/4
Total gallon of honey used for loaves of bread and cookies
= 1/6 + 1/4
= (4+6)/24
= 10/24
= 5/12
Total gallons of honey left over = Gallon of honey remaining - gallon of honey used
= 3/4 - 5/12
= 9-5/12
= 4/12
= 1/3 gallon
Gallon of honey leftover = 1/3 gallon
