Answer:
∠EGF = 90°
Explanation:
Question is incomplete as the attachment is missing.
To solve this I'll make an assumption that ∠EGF is an angle inscribed in the circle.
Given that
Line EF is a diameter;
Then the arc formed by EF is 180° (semi circle).
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
So, the inscribed angle
Arc EF = 2 * ∠EGF
Make ∠EGF the subject of formula
∠EGF = ½ EF
∠EGF = ½ * 180°
∠EGF = 90°
Tectonic hazards do more than cause damage. Through extreme pressure and heat, new resources are formed. Many of these resources are used in transportation and commerce. One of the biggest benefits of volcanoes is extremely fertile soil. Volcanoes also help provide many of the different metals that contribute to a wide spectrum of technology and culture. Copper, gold, silver lead and zinc are all metals developed from magma sources. These naturally-occurring ores are a positive result of tectonic hazards.
Tectonic hazards provide the oil and natural gas that is used all around the world. As tectonic plates press against each other, the pressure not only forms mountains, it also forms oil deposits. When plant matter enters the deposits, coal is formed. This same pressure and heat provide geothermal heating to entire communities across the globe. Many countries rely heavily on geysers for heating.
Scientists are more capable in the 21st century of being able to calculate and anticipate tectonic hazards before they occur. While it is not completely accurate, this knowledge is used to design safer buildings and evacuation plans.

Answer:
b.- earlier; west to east.
Explanation:
Actually our planet, as the rest the planets in our Solar System (except Jupiter) they turn from east to west, that is, this is the way that our clockwise works.
That is the reason that the city A that is at the west of the city B, will have an hour earlier than the city B. (check the image as an example).
But if there is a person at the North Pole, it will seen the otherwise ( clockwise) because of the reference point, that is at the top of our planet.
Hope this info is useful.
