correct order of abundance of oxygen suphur magnesium and calcium in the earth crust?

Options

A. `ogtcagtmggts`
B. `SgtOmggtCa`
C. `CagtOgtSgtmg`
D. `mggtCagtSgtO`

Answer

To determine the correct order of abundance of oxygen, sulfur, magnesium, and calcium in the Earth's crust, we can follow these steps:

### Step 1: Identify the Abundance Percentages
We need to know the approximate abundance percentages of each element in the Earth's crust:
- **Oxygen (O)**: 46.6%
- **Calcium (Ca)**: 3.6%
- **Magnesium (Mg)**: 2.1%
- **Sulfur (S)**: 0.03%

### Step 2: Arrange the Elements in Descending Order
Now, we will arrange these elements based on their abundance from highest to lowest:
1. **Oxygen (46.6%)**
2. **Calcium (3.6%)**
3. **Magnesium (2.1%)**
4. **Sulfur (0.03%)**

### Step 3: Write the Correct Order
The correct order of abundance of these elements in the Earth's crust is:
- **Oxygen > Calcium > Magnesium > Sulfur**

### Final Answer
Thus, the correct order of abundance of oxygen, sulfur, magnesium, and calcium in the Earth's crust is:
**Oxygen > Calcium > Magnesium > Sulfur**
