Answer:
A. It helped sailors steer around rocky coasts.
Explanation:
An astrolabe is an elaborate inclinometer. An inclinometer is an instrument used for angles of slope, elevation, or depression with respect to gravity's direction. It is also used as a tilt sensor, tilt indicator, slope meter, slope gauge.
<em>A. It helped sailors steer around rocky coasts.</em>
Rocky coasts are dangerous. In order to maneuver them, the sailors used an astrolabe. This helped them to understand the angles of slopes, elevation, depression of several rocks on sea.
<em>B. It aided navigators in predicting the weather.</em>
An astrolabe cannot predict the weather.
<em>C. It allowed sailors to know their north-south location.</em>
A compass is used for this purpose.
<em>D. It kept crews from getting sick.</em>
An astrolabe is not a medicinal equipment.
Answer:
Examples of economic impacts include farmers who lose money because drought destroyed their crops or ranchers who may have to spend more money to feed and water their animals. ... Plants and animals depend on water, just as people do. Drought can shrink their food supplies and damage their habitats.
Determine the general wave and longshore sediment transport directions by determiing where the sand is against where it is eroding, is heaping up.
from the top to the bottom
- The direction of beach drift
- Groyne
- The incoming wave direction
-The direction of the longshore current
<h3>What is longshore sediment transport?</h3>
- The collective movement of beach and nearshore sand parallel to the shore caused by the combined action of tides, wind, and waves, as well as the shore-parallel currents produced by them, is referred to as longshore transport.
- Usually, these forces cause sand to move practically continuously, either in bedload flows or suspension.
- This happens in an intricate, three-dimensional pattern that changes quickly over time.
- Sand in the area of interest may occasionally have an upcoast component whereas other sand is often migrating downcoast.

The coordinates of these endpoints can help us find the length and the midpoint, or the point that is halfway between the two endpoints, of the line segment. We can calculate the length of a line segment by using the Distance Formula, and we can calculate the midpoint of a line segment by using the Midpoint Formula.
