Natural phenomenan known as Aurora Boriolis is due to

Options

A. trapping of charged particles from solar flare in the magnetic field of earth
B. trapping of charged particles from solar flare in the electric field of earth
C. both
D. none

Answer

To solve the question regarding the natural phenomenon known as Aurora Borealis, we will analyze the options provided and understand the underlying physics.

### Step-by-Step Solution:

1. **Understanding Aurora Borealis**:
- Aurora Borealis, also known as the Northern Lights, is a natural light display predominantly seen in high-latitude regions around the Arctic and Antarctic.

2. **Identifying the Cause**:
- The phenomenon occurs due to the interaction of charged particles emitted by the sun (solar flares) with the Earth's magnetic field.

3. **Analyzing the Options**:
- **Option 1**: Trapping of charged particles from solar flare in the magnetic field of Earth.
- **Option 2**: Trapping of charged particles from solar flare in the electric field of Earth.
- **Option 3**: Both.
- **Option 4**: None.

4. **Evaluating Option 1**:
- Solar flares release high-energy charged particles (mostly electrons and protons) into space. When these particles reach Earth, they are influenced by the Earth’s magnetic field, which traps and directs them towards the polar regions.

5. **Evaluating Option 2**:
- The electric field of Earth does not play a significant role in trapping these charged particles. The primary interaction is with the magnetic field.

6. **Conclusion**:
- Given that the charged particles are primarily trapped and directed by the Earth's magnetic field, the correct answer is **Option 1**: Trapping of charged particles from solar flare in the magnetic field of Earth.

### Final Answer:
The natural phenomenon known as Aurora Borealis is due to the trapping of charged particles from solar flares in the magnetic field of Earth.
