To represent this information on a 10-by-10 grid, which consists of 100 squares, we need to allocate the squares based on the percentages given. Here's a step-by-step guide:
1. Calculate the Number of Squares for Each Section:
- Total water coverage: 70% of the Earth's surface is covered by water. On a 100-square grid, this means [tex]\(70\)[/tex] squares.
- Pacific Ocean: 32% of the Earth's surface is covered by the Pacific Ocean. On a 100-square grid, this means [tex]\(32\)[/tex] squares.
- Atlantic Ocean: The Atlantic Ocean covers about half of the Pacific Ocean's area. Half of [tex]\(32\)[/tex] squares is [tex]\(16\)[/tex] squares.
2. Sum of Squares for Water Bodies:
- The Pacific Ocean and the Atlantic Ocean together cover [tex]\(32 + 16 = 48\)[/tex] squares.
- The remaining surface area of water (which includes other oceans and water bodies) would be [tex]\(70 - 48 = 22\)[/tex] squares.
3. Representing on a 10-by-10 Grid:
- Out of 100 squares:
- [tex]\(70\)[/tex] squares represent water.
- [tex]\(30\)[/tex] squares represent land (since the total land is the remaining part from 100 - 70).
4. Color Coding for Clarity:
- You could use different colors or shades to distinguish between the areas:
- Blue for water (total 70 squares).
- Dark Blue for the Pacific Ocean (32 squares within the Blue area).
- Light Blue for the Atlantic Ocean (16 squares within the Blue area).
- Green for land (30 squares).
Example Representation on the Grid:
Since drawing the actual grid here isn't feasible, I'll describe a way to conceptualize it:
- Split the grid into two major parts: water (70 squares) and land (30 squares).
- Within the water part:
- Assign 32 squares to the Pacific Ocean.
- Assign 16 squares to the Atlantic Ocean.
- Assign the remaining 22 squares to other water bodies.
Here's a more detailed suggestion. If you fill the grid row by row, it could look something like this:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|------|------|------|------|------|------|------|------|------|------|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Water|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Water|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Water|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Water|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Water|
| Water| Water| Water| Water| Water| Water| Water| Water| Water| Land |
| Land | Land | Land | Land | Land | Land | Land | Land | Land | Land |
| Land | Land | Land | Land | Land | Land | Land | Land | Land | Land |
| Land | Land | Land | Land | Land | Land | Land | Land | Land | Land |
| Land | Land | Land | Land | Land | Land | Land | Land | Land | Land |
- Within the 70 blue (water) cells, you can label 32 cells (dark blue) as Pacific, and 16 cells (light blue) as Atlantic.
This is a rough textual representation. A graphical grid would more clearly show these areas by visually contrasting the differently colored sections.
