Given that the distance on photo is 5.2cm and distance on the map is 3.4cm. a. Calculate photo scale b. Using the same distance on photo with photo scale of 1:50 000. Calculate distance on the map. (15 marks) Show all the workings​

Answers

Answer 1

The vertical exaggeration of the cross section between A and B is 1:4000.

How to calculate the vertical exaggeration?

From the information, the given scale is 1cm:40m. We'll convert 40m to cm. This will be:

= 40 × 100 = 4000cm

Therefore, the vertical exaggeration is 1:4000.

The distance on the photo is 5.2cm and the distance on the map is 3.4cm. Therefore z the photo scale will be:

= 5.2:3.4.

= 52/34

= 26:17

= 1:0.6538

Lastly, the distance on the map will be:

5.2cm:(50000 × 5.2)

5.2cm:260000cm.

5.2cm:2.6km

The distance on the map is 2.6km.

Four why is understanding the structure of the earth important​

Answers

Answer:

understanding the structure of the earth is important to developing the ecosystem and allowing favorable conditions to occur naturally

We rely on the Earth for valuable resources like soil, water, metals, industrial minerals, and energy, and we need to know how to acquire and harness these resources in a sustainable manner. By researching rocks and the fossils they contain, we may learn about the evolution of our environment and the life that exists within it. The production of rock, mountains, volcanoes, and earthquakes is influenced by plate tectonics. All of these things, as well as the mechanisms that created the Earth and continue to drive plate tectonics, can be learned through studying the Earth's innards. If we didn't understand the Earth, we wouldn't be here. There would be nothing like what you’re seeing right now.

An unsaturated air parcel has a temperature of 25°C at the ground level. The surrounding environmental temperature at the ground level is 24°C. Meanwhile, the dew point temperature is 9°C and the environmental lapse rate is 15°C/1000m. Can the air parcel rise to 2000 meters and form clouds when rising? Why or why not? If yes, at what elevation does the cloud start to form? (DALR = 10°C/1000m, MALR = 6°C/1000m)

Answers

If this air rises as unsaturated (dry) air from 1000 mb, determine its temperature at 500 mb by following the solid, straight green dry adiabatic lapse rate line passing through the starting point, up to 500 mb. At 500 mb, the temperature of the unsaturated air parcel is about [(–5)(–35)(–45)] °C. 2.

Compare the present length of the meandering Souris River course shown on the map with the length of a river flowing down this valley if it were not meandering. (You can measure the distance with a piece of string, or your instructor can show you a more precise method.) (a) (b) Length of present meandering course: Length of a straight course down the valley:

Answers

The length of the meandering course of the Souris River is approximately 70 m, while the length of a river flowing in a straight line is approximately 20 m.

What is a meandering river?

A meandering river is a river that is characterized by having a course with several turns that make it look like the movement of a snake.

These rivers generally change the shape of their course by the action of sedimentation. However, the serpentine form will always stand out.

How does the length of a meandering river compare to a river that flows in a straight line?

As shown in the diagram, the length of a meandering river should be measured by segments between its curves, on the other hand, the river flowing in a straight line can be measured in a unified way or by segments.

Additionally, it can be seen how the meandering river has a greater length in the same distance than the river that flows in a straight line.

Note: This question is incomplete because the map is missing. However I can answer it based on my general prior knowledge.
