Terrestrial planets, like Earth and Mars, are primarily composed of rocks and metals, giving them a solid surface. The rockiness allows for the formation of features such as mountains, valleys, and canyons, while metals contribute to their density and structure, making them distinct from their gas giant counterparts. Understanding the differences between terrestrial and gas giant planets is essential for space exploration and planetary science. While terrestrial planets may have surface features and potential for habitability, gas giants often have thick atmospheres and are known for their colorful cloud bands and immense storms, presenting unique phenomena worth studying!
