The total force in each direction has to be the same.
The total force of the blue team is
(220 + 340 + 180 + 560) = 1,300 N
The three members of the red team add up to
(250 + 160 + 420) = 830 N
In order to exactly match the 1,300 N of the blue team,
the fourth red-team guy must contribute an additional
(1,300 - 830) = 470 N .
Answer is Answer is E , using the right hand rule
Answer:
Gwen’s assumption of asteroid hit as long term change is incorrect. Asteroid hit is not a long term change, instead, it is a short term change.
Explanation:
Examples of short term changes are drought, flood, volcanic eruption, etc. A short term change occurs quickly and can immediately affect organisms but it doesn’t become a reason for species extinction. The effects of a short term change don’t prevail over a long span of time.
Examples of long term changes are ice age, global warming, deforestation, etc. Unlike a short term change, it takes time but the consequences are far-reaching. It can lead to species extinction.
In this question, asteroid hit is a quick and unexpected hazard, unlike the slow long term environmental changes.
When the two plates converge or collide they start to build pressure and slowly they lift up and create mountains
