Predicting where an earthquake epicenter will occur is easier because are patterns to look at due to the fact that they always occur near plate boundaries. Predicting when they will occur is difficult because they do not follow any certain pattern.
Answer:
After reading the statement for answer, I noticed that some were true and some were false. So, I'll assume your question is related to that fact.
Here's an analysis of the statements:
Ancient civilizations once lived along the Nile.
TRUE. That's why we encounter the pyramids in that region.
Fertile lands surround the Nile.
TRUE, since the Nile is THE most important source of water in the area, it's logical for it to be the location of agriculture.
Few people live near the river.
FALSE. In Ancient times and today, the Nile shores host most of the population of Egypt, a large part of the country being essentially a chunk of the Sahara desert.
The Nile provides irrigation for surrounding farms.
TRUE. The Nile is virtually the only source of abundant water in the area.
The Nile runs through Libya and Tunisia.
FALSE. Libya and Tunisia are WEST of the country of Egypt and have nothing to do with the Nile.
So, depending if you had to find the TRUE or FALSE statements in this list, make your pick. I hope that helps.
The water cycle or hydrologic cycle is the continuous movement of water between the earth's surface and the air. Water molecules move from the atmosphere (or air) to the earth's surface and back again. Water moves from the atmosphere to the earth's surface via rain, snow, sleet or hail. It moves back to the atmosphere via evaporation. The sun's energy is the catalyst for the movement of water between the atmosphere and the earth's surface.
Answer:
The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.
Answer: B. the amount of fresh water required to mix and dilute pollution in the water.
Explanation:
a grey water footprint is the volume of fresh water that has ben assimulated to pollutants baced on back ground concentration and compisision it also test ambiant water standards to see the quality of the water it has a certain standered that has to be exceded in order to pass as clean water the cleaner the better it is for the ecosystem the minerals and life need the freshest water to drink (no that just is for fresh water sorces) but it is also used for the acidity of the ocean it needs to stay a certain saltyness or the fish and aquatic life will have to relocate or they will just die.
