Answer:
5.8 units
Explanation:
The sum of angles in a triangle is 180°
<F+35°+65°=180°
<F+100°=180°
<F=180°-100°
<F=80°
Using the sine rule:
We solve for g to get:
Option A is correct
Answer:
a. because the region is located far from the equator, the amount of sunlight the region gets will be reduced. Because of this low intensity of sunlight the region receives the average temperature of the region will be very low at winter and a little above 0°C at summer.
b. Polar cell. The air above the surface of the station is cool and dry giving rise to a very cold climate in the region
c. 1 being a mountainous region, the air will be cool favoring a lot of precipitation
2. The ocean can also affect the temperatures, as they have a high heat capacity, so absorb heat in the summer and release it in the winter. They also cause lots of evaporation resulting in wet weather.
d. 1. ozone layer stops harmful UVB and UVC rays from reaching the surface, which can kill all living things,
2. The ozone layer also allows UV-A rays to get through, which are necessary for primary production, and therefore the support of all life on earth by food, nutrients, and oxygen.
Answer:
Explanation:
As plates move apart at the divergent plate boundary the release of pressure produces partial melting of the underlying mantle. This molten material, known as magma, is basaltic in composition and is buoyant. As a result, it wells up from below and cools close to the surface to generate new crust
The geologic time scale is divided into eons, eras, periods, and epochs (EHP-uhks). Unlike divisions of time such as days or minutes, the divisions of the geologic time scale have no fixed lengths. Instead, they are based on changes or events recorded in rocks and fossils.
