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.
The answer is: at a rate between 2 meters (6.5 feet) and 800 meters (2600 feet) per year
There are several factors that can influence these movement, including factors such as currents, global temperature, gravity, etc. Due to the combination of these various factors, currently the antarctic ice sheet has lost around 20,800 square miles of sea ice per year,
Answer:
People choose to settle along the coast because the interior of these countries is not suitable for life.
Explanation:
The countries in Northern Africa like Libya, Morocco, Algeria, and Tunisia, have almost all of their populations settled along or very near the coastlines. There are slight variations among the population patterns in these countries, but the general rule, except in Morocco, is that the interiors have little to no population and settlements.
The reason for this is very simple, lack of living conditions in the interior. While the coastline has multiple benefits for the people, like Mediterranean climate, patches of good soil, access to sea, easy movement of goods and people, the interior is the total opposite. The inteior is a hot desert, part of the Sahara Desert. There is little to no water, no soil, no sources of food, little to no natural resources, no infrastructre, and very dangerous sandstorms.
Answer:
W°= 136
Explanation:
Here,
we get:
The base angles equal since it is isosceles triangle.
W°=68+68 (the exterior angle is equal to the sum of its two opposite interior angles.)
=136
