Read the given statements and select the correct option.
Statement 1 : A spaceship, while entering the Earth's atmosphere is likely to catch fire.
Statement 2: The temperature of the upper atmosphere is very high.

Options

A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B. Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C. Statement 1 is true but statement 2 is false.
D. Both statements 1 and 2 are false.

Answer

To solve the question, we need to evaluate the two statements provided:

**Statement 1:** A spaceship, while entering the Earth's atmosphere, is likely to catch fire.

**Statement 2:** The temperature of the upper atmosphere is very high.

### Step-by-Step Solution:

1. **Understanding Statement 1:**
- When a spaceship re-enters the Earth's atmosphere, it travels at very high speeds.
- As it descends, it encounters atmospheric friction, which generates a significant amount of heat.
- This heat can cause the materials of the spaceship to ignite, leading to the phenomenon where the spaceship appears to catch fire.

**Conclusion for Statement 1:** This statement is true.

2. **Understanding Statement 2:**
- The term "upper atmosphere" generally refers to the layers of the atmosphere that are higher up, such as the stratosphere and mesosphere.
- In these upper layers, the temperature actually decreases with altitude, and it is much colder than at lower altitudes.
- Therefore, the assertion that the temperature of the upper atmosphere is very high is incorrect.

**Conclusion for Statement 2:** This statement is false.

3. **Final Evaluation:**
- Since Statement 1 is true and Statement 2 is false, we can conclude that the correct option is that Statement 1 is true, and Statement 2 is false.

### Final Answer:
- Statement 1 is true, and Statement 2 is false.
