Answer :

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.
