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:
Correct answer is Wegener had no compelling mechanism to explain what would cause the continents to move.
Explanation:
A is not correct as through his researches he presented his theory to other scientist.
B is not correct as Wegener was very educated, and was even even working as a professor at University.
C is correct that although he presented his theory, he couldn't explain totally how it happened.
D is not correct as during his lifetime his theory wasn't widely accepted. That happened 20 years after his death.
Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
The appropriate answer is B. DIVERGENT. Divergent margins occur where two oceanic plates are pulling apart or it can occur where a Continental landmass is pulling apart.
As oceanic plates pull apart magma up wells from the mantle and new crust is formed along what is called a spreading ridge. The Mid Alantic ridge is an example of a spreading ridge where new oceanic crust is being formed.
