1. Read the following passage and answer the questions that follow:

Passage:

The sun is a star that is located at the center of our solar system. It is a giant ball of hot gas that provides heat and light to the planets in our system. The sun is about 93 million miles away from Earth, but its light only takes about 8 minutes to reach us.

The sun is made up of several layers. The innermost layer is the core, where nuclear fusion occurs. This is where hydrogen atoms combine to form helium, releasing a tremendous amount of energy. Surrounding the core is the radiative zone, where energy is transported by photons. Above the radiative zone is the convective zone, where energy is transported by the movement of hot gas.

The sun’s outermost layer is called the photosphere. This is the layer that emits light and heat. Above the photosphere is the chromosphere, which is a thin layer of hot gas. Finally, the outermost layer is the corona, which is a halo of plasma that extends millions of miles into space.

Questions:

1. What is the sun?
2. How far is the sun from Earth?
3. What is the core of the sun?
4. How is energy transported in the radiative zone?
5. What is the outermost layer of the sun called?

Answers:

1. The sun is a star located at the center of our solar system.
2. The sun is about 93 million miles away from Earth.
3. The core of the sun is where nuclear fusion occurs.
4. Energy is transported by photons in the radiative zone.

5. The outermost layer of the sun is called the corona.

Passage:

Mount Everest is the highest mountain in the world, with a peak that reaches 29,029 feet above sea level. It is located in the Himalayas, on the border between Nepal and China. Mount Everest is a popular destination for climbers, but it is also a dangerous one.

The first successful ascent of Mount Everest was made by Sir Edmund Hillary of New Zealand and Tenzing Norgay, a Sherpa of Nepal, in 1953. Since then, many climbers have attempted to reach the summit, but not all have been successful. Climbing Mount Everest is a challenging and physically demanding feat that requires careful planning and preparation.

The weather on Mount Everest can be extreme and unpredictable. Temperatures can drop to -40 degrees Fahrenheit, and winds can reach speeds of over 100 miles per hour. Climbers must be prepared for these harsh conditions and have the necessary equipment and supplies to survive.

Questions:

1. Where is Mount Everest located?
2. Who made the first successful ascent of Mount Everest?
3. What is required to climb Mount Everest?
4. What are the extreme weather conditions on Mount Everest?
5. Why is climbing Mount Everest dangerous?

Answers:

1. Mount Everest is located in the Himalayas, on the border between Nepal and China.
2. Sir Edmund Hillary of New Zealand and Tenzing Norgay, a Sherpa of Nepal, made the first successful ascent of Mount Everest.
3. Climbing Mount Everest requires careful planning and preparation.
4. The extreme weather conditions on Mount Everest include temperatures dropping to -40 degrees Fahrenheit and winds reaching speeds of over 100 miles per hour.
5. Climbing Mount Everest is dangerous due to the extreme weather conditions, physical demands, and the risk of altitude sickness and avalanches.
