Question is incomplete, so the complete question is as follows:
How did the use of the environment enable early human clans to develop advances in food production?
A. Villagers learned to grow new food quickly when flooding occurred.
B. Villagers learned to use tools to create a food surplus throughout the year.
C. Villagers learned to harvest food for immediate consumption instead of storage.
D. Villagers learned to compete for food through hunting and fishing methods in multiple locations.
Answer:
A. Villagers learned to grow new food quickly when flooding occurred.
Explanation:
Natural disasters are one of the major challenges in food production. Environemntal challenges such as drought and flooding made villagers and people to lear or find new techniques to grow food faster in that situation for their survival.
A flood could destroy the entire food supply but villagers learned to deal with the situation and learned how to take advantage of these natural disasters.
Hence, the correct answer is "A".
1) Motion can be different depending on the relevant speeds or positions of the observer. For example, if you are riding in a car traveling at 20mph, a different car traveling beside you at 30mph won't seem to be going that fast because the difference in the two speeds is only 10mph. But if you are standing in one spot and a car speeds past you at that same speed, it will appear to be moving much faster than before because the difference between your speed and the car's speed is much greater.
2. You could describe is as linear motion if the car is traveling in a straight line, circular motion when the car is turning, and even rotational motion is describe the motion of the car's tires
It means that the satellite's orbital period is equal to the Earth's rotation period ... roughly 23 hours 56 minutes 4 seconds ... so that the satellite always stays over the same longitude.
IF that satellite's orbit has also been carefully placed over the equator, THEN the satellite is in a 'geostationary' orbit. It appears motionless in the sky, and can be used to sell 900 channels of TV to people with little dishes that they never need to move.
3.) St. Petersburg
is the port at the head of the Gulf of Finland
