Answer:
In a situation in which You land your inflatable boat on a sandbar at high tide in Southeast Alaska, which has a large semi-diurnal tide. You intend to be away from the boat for 12 hours but come back early after only 8 hours. Your boat is, unfortunately, 400m from shore.
You will have to wait B) 4 hours and 25 minutes
to be able to use your boat
Explanation:
The reason behind this is that the water movement makes objects floating in its surface move at a certain rhythm. Generally, this measure is variable but after having the data of 400 m movement in 8 hours. We just have to divide to find out the speed at which the water moves the objects on its surface. We divide 400 between the 8 hours to obtain. 50 meters of distance advance in a single hour. Therefore in 4 hours and 25 minutes, it will be at the correct distance to be reached out and used.
Answer:

Explanation:
Answer: Sillimanite, Andalusite, Kyanite and Staurolite
Explanation:
This are the four main minerals that forms in metamorphic rocks and indicates metamorphism.
Sillimanite forms at a high temperature condition, andalusite forms at a moderate temperature and pressure condition, and lastly, kyanite forms at a high pressure condition. Staurolite also forms at high temperature-pressure condition.
This four minerals forms when a rock undergoes metamorphism and are usually found in metamorphic rocks such as schist, gneiss and granulite.
