Answer:
three half-lives
Explanation:
Converting 12.5% to decimal gives 0.125
If one half life is 0.5.
0.5*0.5*0.5 gives 0.125
Thus 3-half lives has been elapsed
In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.
Answer:
Below
Explanation:
The fault is always younger than the rocks it cuts across because in order to have cut across those rocks they have to have existed there already, making them older
Answer:
c) on the outer banks of the meander loops
Explanation:
The meandering streams form in places that have low elevation and are flat, covered with softer sediments. The stream starts as mostly straight, but as time passes it erodes one of the banks, while depositing on the opposite bank, become very curvy, snake-like in shape, thus a meandering stream. In the meandering streams, the water has the most velocity at the outer banks. This results in greater erosion of the outer banks, and this part constantly moves outwards. In the same time, the water has the least velocity at the inner bank, resulting in deposition of the material that it has been carrying with it, so this part constantly grows inwards.
Answer:
Explanation:
Freshwater resources are not evenly distributed around the planet because there are some places where precipitation doesn't take place like deserts or tundra's. In rainforests there is an abundant reservoir of water.
Hope this helps.
