The development of the calander shows they can divde the number of minutes hours days month etc in a year. Development of the pyramids shows geometry and engineering. look up to make sure.
Answer:
Compared to the valley, the ridge is relatively wet and cool.
Explanation:
The ridge is relatively wet and cool in comparison with the valley. Due to the mountains that surround the valley, the cool air does not enter the valley. This makes the valley hotter in contrast with the ridge. Also, it makes the ridge wet owing to the pressure and the low temperature that the air has.
You would be describing its Longitude because longitude lines go up and down.
The desert gets less than twenty inches of rainfall per year.
Answer:
510
Explanation:
Recurrence interval involves the average estimated time or average spacing between events. It helps to estimate the time probability of an event taking place.
Calculating the recurrence interval we have:
![[(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4](https://tex.z-dn.net/?f=%20%5B%28820%20-%20260%29%20%2B%20%281200%20-%20820%29%20%2B%20%282100%20-%201200%29%20%2B%20%282300%20-%202100%29%5D%20%2F%204%20)


After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.
