These are the Rift Valley, the Eastern Highlands, the Eastern Lowlands, and the Western Highlands and Western Lowlands. The largest and most rocky topographic region of Ethiopia is the Western Highlands. The North Central massifs, which make up the majority of the area and are the highest in Ethiopia, are the most spectacular.

Lowland areas in Ethiopia are those that are located below 1,500 metres. The brief for this rapid review was to concentrate primarily on the Afar and Somali regions, as well as the lowland parts of Oromia and SNNPR, even though they cover eight of the country's administrative regions.

Answer:

Explanation:

If Jackson used 4 gallons of gas to drive 80 miles to Crabclaw Beach, we can calculate his gas mileage as follows:

Gas mileage = distance / gas used

Gas mileage = 80 miles / 4 gallons

Gas mileage = 20 miles per gallon

Using this gas mileage, we can calculate how many gallons of gas Jackson will use to drive 100 miles to Mount Highmore:

Gas used = distance / gas mileage

Gas used = 100 miles / 20 miles per gallon

Gas used = 5 gallons

Therefore, Jackson will use 5 gallons of gas to get to Mount Highmore if he uses gas at the same rate as he did for his trip to Crabclaw Beach.

"Introduction

Cape Coast Metropolitan is one of the largest cities in Ghana with a population of about 170,000 people. It is located in the Central Region and has a significant impact on the environment due to human activities. As such, environmental sustainability is a crucial concern for the metropolitan area. This paper will discuss five economic planning instruments that can be applied to enhance environmental sustainability in Cape Coast Metropolitan.

1. Environmental Impact Assessment (EIA)

Environmental Impact Assessment is a planning tool used to assess the potential environmental impact of proposed projects. EIA provides an opportunity to identify potential environmental risks and propose mitigation measures to avoid or minimize adverse environmental impacts. In Cape Coast Metropolitan, EIA can be used to assess the potential environmental impacts of development projects such as construction of buildings, roads, and other infrastructure. For example, before the construction of a new housing project, an EIA can be conducted to assess the potential impact on the environment, including air and water pollution, loss of biodiversity, and land degradation. The EIA can identify potential mitigation measures such as the use of green building techniques, the implementation of waste management plans, and the protection of natural habitats.

2. Environmental taxes

Environmental taxes are levies imposed on activities that have a negative impact on the environment. In Cape Coast Metropolitan, environmental taxes can be used to discourage activities that contribute to environmental degradation. For example, a tax can be imposed on industries that emit pollutants into the air or water. The tax can provide an incentive for industries to adopt cleaner production methods that reduce the emission of pollutants. Additionally, a tax can be imposed on the use of non-biodegradable materials such as plastics. The tax can provide an incentive for individuals and businesses to switch to more environmentally friendly alternatives such as reusable bags.

3. Tradable permits

Tradable permits are a market-based instrument that can be used to limit the amount of pollution emitted by industries. Under this system, the government sets a limit on the amount of pollution that can be emitted by an industry. The industry is then issued a number of permits equal to the allowable amount of pollution. If an industry emits less pollution than its allocated permits, it can sell the surplus permits to other industries that exceed their permitted emissions. In Cape Coast Metropolitan, tradable permits can be used to limit the amount of pollution emitted by industries such as manufacturing and transportation. This can encourage industries to adopt cleaner production methods and reduce their emissions to stay within their allocated permits.

4. Subsidies

Subsidies are financial incentives provided by the government to encourage certain activities. In Cape Coast Metropolitan, subsidies can be used to promote environmentally friendly activities such as the use of renewable energy sources. For example, the government can provide subsidies to individuals and businesses that install solar panels or wind turbines. This can encourage the adoption of renewable energy sources, which can reduce the reliance on fossil fuels and the emission of greenhouse gases. Additionally, the government can provide subsidies for the development of public transportation systems such as buses and trains. This can encourage the use of public transportation, which can reduce the emission of pollutants from private vehicles.

5. Green procurement

Green procurement is a policy that encourages the purchase of goods and services that have a lower environmental impact. In Cape Coast Metropolitan, green procurement can be used to promote sustainable consumption patterns. For example, the government can adopt a policy of purchasing office supplies that are made from recycled materials. Additionally, the government can encourage the purchase of locally produced goods and services, which can reduce the emission of greenhouse gases associated with transportation. Green procurement can also be applied to construction projects, where the government can require the use of environmentally friendly building materials.

Conclusion

In conclusion, environmental sustainability is a critical concern for Cape Coast Metropolitan. The city can use a range of economic planning instruments to enhance environmental sustainability. These instruments include environmental" (ChatGPT, 2023)

Explanation:

A physical geographer might designate regions based on Optio B. continents, mountains, and bodies of water.

This approach focuses on the physical characteristics of the Earth's surface and how they influence the distribution of landforms, climate patterns, and natural resources. By considering these physical features, geographers can identify distinct regions with unique characteristics and processes.

Continents play a significant role in regional designation as they are large landmasses separated by oceans. Each continent has its own set of physical features, such as mountain ranges, rivers, and deserts, which contribute to the formation of distinct regions. For example, the continent of Africa is known for its vast savannahs, while South America is home to the Amazon rainforest and the Andes Mountains. These physical features shape the climate, vegetation, and animal life in these regions.

Mountains also contribute to regional designation as they create barriers that affect climate and vegetation patterns. For instance, the Himalayas in Asia have a profound impact on the monsoon system and the distribution of precipitation across the region. Mountains can also act as natural borders between regions, influencing cultural and economic interactions.

Bodies of water, such as oceans, seas, and lakes, also play a crucial role in regional designation. They affect climate, provide transportation routes, and influence economic activities like fishing and trade. For instance, the Mediterranean Sea has shaped the climate and cultural development of the surrounding countries, creating a distinct region known as the Mediterranean Basin.

Overall, by considering continents, mountains, and bodies of water, physical geographers can identify regions based on the natural characteristics and processes that shape the Earth's surface. This approach helps in understanding the relationships between physical features, climate, ecosystems, and human activities within different regions. Therefore, Option B is Correct.

Answer:Suspension bridges were important in the Inca Empire because they allowed for easier travel and transportation of goods, as well as providing an advantage in military strategy.

Explanation:

The Inca Empire was an ancient civilization that flourished in South America from the 13th to the 16th century. The Inca people were known for their advanced engineering and infrastructure, including their impressive network of suspension bridges.

Suspension bridges were crucial in the Inca Empire because they helped connect different regions of the empire and allowed for easier travel across difficult terrain. The Inca people were skilled in weaving ropes and cables from natural materials like grass and straw, which they used to construct the bridges.

One famous example of an Inca suspension bridge is the Q'eswachaka Bridge, which is still standing today in modern-day Peru. This bridge was built using traditional Inca techniques and is made entirely of woven grass and straw cables. It stretches over 100 feet across a deep canyon and is still used by locals today.

Suspension bridges also played an important role in the Inca Empire's military strategy, as they allowed troops to quickly cross rivers and valleys during battle. They were also used to transport goods like crops, textiles, and precious metals across the empire.

Suspension bridges were important in the Inca Empire because they allowed for easier travel and transportation of goods, as well as providing an advantage in military strategy. The Inca people's impressive engineering skills helped them construct these impressive structures, which continue to amaze and inspire us today.

Migration begins at the area called the point of origin.

The point of origin is the initial location from where a migratory journey begins. It serves as the starting point for individuals or groups of organisms as they embark on their seasonal or long-distance movements. This area is typically characterized by favorable conditions, such as abundant resources or suitable breeding grounds that trigger the need for migration.

It acts as a launching pad for migratory routes and plays a crucial role in determining the direction and timing of the migration. The point of origin can vary on species or context, ranging from specific breeding sites for birds to specific regions for human migration patterns.
