To find the answers to these questions, you can conduct research using reliable sources such as books, articles, or government websites. Here are the explanations for each question and some tips on how to find the answers:
1. One of the first attempts to build a big dam took place in Mesopotamia (modern-day Iraq) around 3000 BCE. You can search for the history of dam construction or the earliest known dams in human history.
2. The important feature located in the middle of this dam was often a spillway, which is a channel or structure designed to release excess water from a dam's reservoir. To find specific examples of ancient dams and their features, you can search for ancient dam construction or ancient irrigation systems.
3. The dam on the Nile River, known as the Aswan High Dam, was a collaboration between Egypt and the Soviet Union. The lake created by this dam is called Lake Nasser, and it covers approximately 310 miles of desert. You can search for the Aswan High Dam or Lake Nasser to find more information about its construction and impact.
4. As the lake levels were rising behind the Aswan High Dam, measures were taken to protect the ancient monuments in the affected area. Many archaeological sites, including the temples of Abu Simbel, were relocated to higher ground to avoid being submerged. Searching for the impact of the Aswan High Dam on ancient monuments or the relocation of Egypt's temples will provide more information.
5. The construction of the Hoover Dam in the United States began in 1931 and was completed in 1935. To find more specific information about the Hoover Dam's completion, you can search for the construction timeline or historical records related to the dam.
6. The city of Los Angeles, California, agreed to purchase the electricity generated by the Hoover Dam once it was completed. Searching for the power agreements or contracts related to the Hoover Dam can provide more information.
7. The Hoover Dam was inaugurated by President Franklin D. Roosevelt on September 30, 1935. You can search for the inauguration ceremony or historical records of the event for more information.
8. The Hoover Dam has a total of 17 generators that create electricity. Each generator is powered by a turbine connected to the dam's water flow. Searching for the specifications or technical details of the Hoover Dam's generators can provide more information.
9. Spillways on a dam are designed to redirect excess water from the dam's reservoir during periods of high inflow or heavy rainfall. They help prevent the dam from overtopping or being damaged by the increased water flow. To find a detailed explanation of spillways and their importance, you can search for dam engineering, spillway design, or the function of spillways in dams.
