Answer:
Blueschist
Explanation:
Blueschists are formed in association with subduction and continental collision and reflect burial to high pressures at relatively low temperatures.

Hello. This question is incomplete. The full question is:
What can scientists learn from magnetic striping patterns? Select the three correct answers.
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
3. the location of ancient faults caused by seismic activity
4. the exact location of the next earthquake along the California coast
5. the direction plates are moving relative to each other
6. the speed of one plate as it subducts below another plate
Answer:
The direction plates are moving relative to each other
The speed of one plate as it subducts below another plate
The location of ancient faults caused by seismic activity
Explanation:
Magnetic striping patterns are very valuable systems for understanding the factors that promote polar variability of the ocean floor. This is because these systems are formed exactly by changes in this polarity, presenting lines (similar to a zebra), which allow scientists to interpret them and have valuable information about the movement of the direction plates towards each other, the speed that a plate reaches the subduz below another plate and the location and old faults that were caused by the existence of seismic activities.
Answer:
Explanation:
Rivers have three sections or courses: the upper course, middle course and lower course. The upper course of a river typically sees much erosion of bedrock in order to achieve the equilibrium mentioned above.
The upper course is also at the highest altitude as this is where the headwaters of the river originate. Rivers in the upper course erode down vertically which often creates a steep channel profile in what becomes the river valley.
The middle course sees a river at a slightly lower altitude than the upper course, but is still maintains a sense of trying to acquire equilibrium in flow and shape. The discharge and velocity of the river still allows the water to erode the banks and chart a course of least resistance through lateral erosion.
The lower course is unique as this is the stage in which a river has reached sea level. Here we find features not found in the middle and upper courses like floodplains and river deltas that have been formed by the sediment deposits of rocks and dirt gathered from upstream.
