What is true about statements X and Y statement X. Deforestation causes global warming.
Statement -Y: Deforestation increases level of green house gas `CO_(2)` in atmosphere.

Options

A. X is correct, Y is wrong
B. X and Y both correct but Y is correct explanation
C. X and Y both correct but Y is not correct explanation
D. X and Y both are wrong

Answer

To analyze the statements X and Y, we will break down the concepts involved in each statement step by step.

### Step 1: Understand Statement X
**Statement X:** "Deforestation causes global warming."
- Deforestation refers to the clearing of forests, which leads to a reduction in the number of trees. Trees play a crucial role in absorbing carbon dioxide (CO₂) from the atmosphere during photosynthesis.
- When forests are cut down, the stored carbon in trees is released back into the atmosphere, contributing to an increase in CO₂ levels.
- Increased levels of CO₂ enhance the greenhouse effect, leading to global warming, which is the gradual increase in Earth's surface temperature.

**Conclusion for Step 1:** Statement X is true.

### Step 2: Understand Statement Y
**Statement Y:** "Deforestation increases the level of greenhouse gas CO₂ in the atmosphere."
- As mentioned, deforestation leads to the release of CO₂ that was previously stored in trees.
- The reduction of trees means less CO₂ is absorbed from the atmosphere, further contributing to the increase in atmospheric CO₂ levels.
- Therefore, deforestation directly correlates with an increase in greenhouse gases, particularly CO₂.

**Conclusion for Step 2:** Statement Y is also true.

### Step 3: Relationship Between Statements X and Y
- Statement Y provides a reason for why Statement X is true.
- Since deforestation increases CO₂ levels (Statement Y), it logically follows that this increase contributes to global warming (Statement X).

**Final Conclusion:** Both statements X and Y are correct, and Statement Y is the correct explanation for Statement X.

### Answer:
Both statements X and Y are true, and Y is the correct explanation for X.
