Answer:
40km
Explanation:
Average speed can be computed with the equation:
So we know the average speed and one of the distances is already given and we need to know how much it traveled after that. The total time the car traveling is 2 hours. Let's plug that in our equation:
Now let's multiply both sides by 2 hours:
Cancel out the hours and multiply:
Subtract 100km from both sides of the equation:
The answer is that these continents were once joined together in one big continent.
All continents were once connected as one supercontinent Pangea. On that supercontinent, many species lived across all the supercontinent, such as mesosaurus. But after continents spread apart, some populations remained on the different parts of the supercontinent. So, some population ended up on South Aamerica, some on Africa, and some on Antartica. The geological theory that explains how continents move through Earth's surface is called c<span>ontinental drift.</span>
Explanation:
A is the correct Answer because when the molecules want to move they have a low concentration
The "small animals diversify quickly" is true about life on Earth at this time.
<u>Option: D</u>
<u>Explanation:</u>
The appearance of the Cenozoic period took place with the vanishing of the dinosaurs, this scenario is nearly 65 million years earlier, which is continued till today. This era has been splited into two periods of time named as the Tertiary and the Quaternary. There were inevitably number of vacant spaces on Planet where animals could survive after the dinosaurs' absence.
Immediately after their extinction, several vacant areas have been studied in nature where animals could flourish. At the start of the Cenozoic the mammals which were small, mouse resembling animals getting scattered rapidly and also diversified quickly in nature, their size also started increasing. Massive elephants and rhinos, sabre-tooth cats and lions, horses and deers quickly got populated in Earth's plains and forests.
