Sure, let's fill in the table comparing the different characteristics of continental crust and oceanic crust.
[tex]\[
\begin{array}{|c|c|c|}
\hline
& \text{Continental Crust} & \text{Oceanic Crust} \\
\hline
1. \text{Rock age} & \text{Old rocks} & \text{Young rocks} \\
\hline
2. \text{Thickness} & \text{Thick} & \text{Thin} \\
\hline
3. \text{Type of Rocks} & \text{Granite, Metamorphic rocks} & \text{Basalt, Gabbro} \\
\hline
4. \text{Density} & \text{Less dense} & \text{More dense} \\
\hline
\end{array}
\][/tex]
Let's walk through each characteristic for clarity:
1. Rock age:
- Continental Crust: Consists of older rocks.
- Oceanic Crust: Consists of younger rocks.
2. Thickness:
- Continental Crust: Is generally thicker.
- Oceanic Crust: Is thinner.
3. Type of Rocks:
- Continental Crust: Predominantly composed of granite and metamorphic rocks.
- Oceanic Crust: Primarily composed of basalt and gabbro.
4. Density:
- Continental Crust: Has less density.
- Oceanic Crust: Is denser.
Each of these characteristics helps in distinguishing and studying the Continental and Oceanic crusts in various geological studies.
