Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 800
x = amount of daughter isotope = 600
a - x = amount left after decay process = amount of parent isotope = (800-600) = 200
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
The rock is 2000785 years old.
Answer:
These islands represent Europe, Africa, Antarctica, Asia, North and south america etc.
Explanation:
An artificial island or a man-made island is an island created by natural means that vary in sizes.
For example Flevopolder in the Netherlands which is an artificial island of 970 kilometers created for reclaiming the land area as the Netherland already is a very small island in the Atlantic ocean.
Lots of islands are formed by China, America, and the middle east to increase their dominance over and increase their military size. Likewise, <u>U.A.E is home to several artificial islands including yas island and Khalifa port. </u>
China has developed its island group in the south china sea. Which is china's strategic planning to meet its population and economic needs of the country. The biggest world island is that in world map form around which small islands are constructed called as Artificial Archipelago, located in the waters of persian gulf.
Construction of these 300 island began in 2003, this project ranges from 14,000 to 42,000 square meters in area. Comprise of sand and stones The islands have beach clubs and airport.
<u>Explanation:</u>
Fault-block mountains are formed by the movement of large crustal blocks when forces in the Earth's crust pull it apart. Some parts of the Earth are pushed upward and others collapse down.
Fault blocks are very large blocks of rock, sometimes hundreds of kilometers in extent, created by tectonic and localized stresses in the Earth's crust. Large areas of bedrock are broken up into blocks by faults.
The process is simple when forces in the Earth's crust pull it apart.
I hope you get the idea thanks.
If you're referring to streams/rivers of water that run independently of another source in the ocean these are referred to as "currents" and can be very powerful depending on their location.
B. Kuwait faced environmental damage during the Persian Gulf War.
