Answer:
immigration help to a country to grow their labor or taxes
Explanation:
Immigrants also make an important contribution to the U.S. economy. Most directly, immigration increases potential economic output by increasing the size of the labor force. Immigrants also contribute to increasing productivity.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
Answer:
Athens had a large and capable navy
Some of the factors would be introduction of non native species, pollution, overgrazing, chemical agents and habitat loss
The anticlines represents ridges or folds of stratified rocks, with the strata being sloping downwards from the crest.
The synclines represent through or folds of stratified rocks, with the strata being sloping upwards from the axis.
Both of these features are formed in the same manner, by compression. They are also part of a same geological occurrence. Both of them are curved, and seen from side perspective, they are representing one whole, and they look like a wave.
The difference is mainly that the anticlines are always above and they slope downwards, while the synclines are always on the bottom and slope upwards.
