Answer:

In the given topography, point A is the northern side at a height of 2690 feet. B is at a height of 2220 feet and location C has a height of 2340 feet. A and B are separated by a horizontal distance of 520 feet, B and C are separated by a horizontal distance of 250 feet and C is located at N35°E of point B.

From the above data, we can demarcate the topography of the area. The area is inclined towards the southern side as when we move from point A to C and C to A the elevation gradually decreases.

Thus, <u>the exposed rock unit in that area dips towards the South and the strike direction of this rock is the East-west direction.</u>

Dip is defined as the angle made by a rock bed with respect to a horizontal line and strike refers to the direction of the line that is formed due to the intersection between a rock surface and a horizontal plane.

Dip and strike always perpendicular to one another.

Answer:

Air rises at the equator, leading to low pressure and rainfall. Global atmospheric circulation creates winds across the planet and leads to areas of high rainfall, like the tropical rainforests, and areas of dry air, like deserts. And for the hazards, Physical removal of the hazard is the most effective hazard control. For example, if employees must work high above the ground, the hazard can be eliminated by moving the piece they are working on to ground level to eliminate the need to work at heights.

Historically, _____.
oee [108]

The correct answer is - 2. Earth's climates have changed and are likely to change in the future.

From what is known for the geologic past of the Earth, our planet's climate has been changing numerous times. The climate on the planet has varied from being predominantly wet tropical climate, to having ice ages, having multiple different climate types at the same time... The reasons for the changes in the Earth's climate are numerous, with the Sun's radiation, tectonic movements and activities, volcanic activity, outside influences like asteroid and meteorite collisions, the vegetation, and all of them have managed to create a very colorful climate history of the planet. This trend of climate change should continue in the future as well, as all of the aforementioned factors are still influencing the climate and on top of that the humans have become a factor in the climate change too.
