Explanation:
The listed options are:
A) Large number different-sized footprints.
B) Plant but no animal fossils.
C) Underwater organisms in dry land.
D) Straight teeth buried below curved teeth.
Discovering fossils of underwater organisms in dry land <u>demonstrates that thousands to millions of years ago, there was a body of water such as an ocean, lake, or river in an area that is now dry land.</u> This gives important insights into what was the Earth's climate at that epoch and how it has changed throughout time.
This discovery could allow researchers to study what the conditions were at that time and why that body of water dried out. Moreover, it could lead to answers of the reasons behind the extinctions or evolution of some underwater organisms.
Answer:
11km
Explanation:
The total distance travelled is the sum of the distance as follows:
- from home to friend's house
- from friend's house back home
- from home to the mall
According to this question;
* I walked from my house to my friend's place and covered 0.5km
* I walked back from my friend's house home in the same 0.5km
* I drove to the mall from my house and covered a distance of 10km
Hence, the total distance covered is 0.5 + 0.5 + 10
= 11km
