Then, you will share and discuss with your classmates your position.

Answers

Some impacts of building roads in rainforests on people and the Earth are:

Increased soil erosion.Deforestation. Increased farming and settlement for people.Increased poaching.

What does building roads in rainforests lead to?

When roads are built in rainforests, there will be increased deforestation because trees need to be cut down to build the roads. As a result of the deforestation, there will be increased soil erosion as well.

Humans will also have more access to the rainforests which will lead to them settling there more and farming which further endangers the forest. Poachers will also increase their activities thanks to more access which would reduce the fauna in the forest.

The heat from the Sun must pass through the vacuum of space before it reaches the Earth. Which process is illustrated in this example?

Answers

What is the relative humidity?

1. 40%

2. 36%

3. 8%

4. 4%

Answers

Based on the readings on the Wet and Dry Bulbs of this weather instrument, the relative humidity is 40%.

What is the relative humidity?

First find the difference between the reading on the wet and dry bulbs:

= Dry bulb temperature - Wet bulb temperature

= 22 - 14

= 8°C

When the difference between these bulbs is 8°C and the temperature on the dry bulb is 22°C, then the relative humidity is 40% as shown in the table attached.

Questions (25 marks) 1. Calculate the vertical exaggeration of the cross section between A and B (Vertical scale - Icm: 40m) (10 marks) 2. 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

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.

Is Human Population too large? Explain your reasoning.

Answers

Answer:

No

Explanation:

There are several reasons as to why population is not too large.

1. Resource crisises, such as food shortages, are less a result of population and more a result of the standard of living. In fact, the countries that have the highest populations are not the countries that consume the most resources. Develop countries with lower populations consume far more than less developed countries with much higher populations, showing that population isn't necessaily the issue.

2. Population drives innovation. Whenever there are more people, there are more minds to think and hands to work, and in general whenever an area has a population boom that is usually followed by a large amount of technological advancement.

3. Population growth is directly related to the demographic transition model, which is a model that describes how population within a country over time. Once a country reaches stage four, the population stops growing. In theory, every single country will eventually hit stage four, meaning that eventually human population will level out and even decrease in the future with development.
