Question

question 31 multiple choice worth 2 points oss 01 scientists have discovered a solar system at a distance of 2000 au from earth. what is the distance, in kilometers, between the new solar system and earth? 300 million kilometers 300 billion kilometers 20 million kilometers 20 billion kilometers question 32 multiple choice worth 2 points tg 01 the diagram below shows two natural processes. process 1 process 2 which of these statements is correct about process 1 and process 2? both processes create mid - ocean ridges. both processes create high mountain ranges. process 1 creates mid - ocean ridges and process 2 creates high mountains. process 2 creates mid - ocean ridges and process 1 creates high mountains.

Explanation:

Question 31

Step1: Know the conversion factor

1 AU (astronomical unit) is approximately 150 million kilometers.

Step2: Calculate the distance

The distance is 2000 AU. So, the distance in kilometers is $2000\times150\times10^{6}=300\times10^{9}$ kilometers = 300 billion kilometers.

Process 1 shows a divergent - plate boundary where new crust is formed, creating mid - ocean ridges. Process 2 shows a convergent - plate boundary where one plate is subducted under another, often leading to the formation of high mountain ranges.

Answer:

300 billion kilometers
