road
Definition
A road is a constructed path that allows for the passage of people, animals, and vehicles. Roads are usually made of materials that are durable and can withstand heavy use. They can be found in all parts of the world, and they play an important role in transportation and communication.
The earliest roads were made of dirt or gravel. These roads were often difficult to travel on, and they were not very durable. In the 19th century, concrete and asphalt roads were developed. These roads are much more durable and can withstand heavy use.
Roads are classified into different types based on their purpose and construction. Major roads, such as highways and interstates, are designed for high-speed travel. Minor roads, such as local streets and roads, are designed for slower traffic.
Roads are an important part of our infrastructure. They allow us to travel from one place to another quickly and easily. They also help to connect different communities and businesses. Roads are essential for our economy and our way of life.
How can the word be used?
The car drove down the road.
Different forms of the word

AQA Science Exam Question and Answer
Question:
Explain the environmental impact of road construction and propose sustainable measures to mitigate its effects.
Answer:
Road construction significantly impacts the environment through various mechanisms. Firstly, habitat destruction and fragmentation can occur as roads disrupt ecosystems and wildlife habitats. Secondly, construction activities generate pollutants, such as sediment runoff, which can degrade water quality in nearby streams and rivers. Additionally, increased impervious surfaces from roads contribute to higher surface runoff, leading to erosion and flooding. Road construction also contributes to deforestation, releases greenhouse gases from machinery and vehicles, and alters local microclimates.
To mitigate these effects, adopting sustainable practices is crucial. Implementing proper planning and environmental assessments can help avoid sensitive areas and minimise habitat disruption. Erosion control measures like sediment ponds and erosion blankets can prevent sediment runoff. Incorporating green infrastructure like permeable pavements and vegetated medians can manage stormwater and reduce flooding risks. Prioritizing the use of energy-efficient machinery and promoting alternative transportation methods can limit carbon emissions. Moreover, reforestation and habitat restoration efforts can help offset the ecological damage caused by road construction.
