Answer:
A planet's density is related to its composition. ... The inner planets are made up mainly of dense, solid rock. The outer planets are composed primarily of gas, so their overall density is lower. However, they are larger in size and much more massive!
Whats the difference between weathering and erosion?
Answer:
The process of weathering wears away rock formations. When rocks are chipped away or shattered, such as when water seeps into a fissure and freezes, expanding and fracturing the rock apart, mechanical weathering occurs. When the chemical makeup of a rock or mineral is altered, chemical weathering can occur. Rainwater combining with limestone, for example, causes chemical weathering. Erosion, on the other hand, happens when small fragments of rock or sand are blown around or become entangled in river currents and scraped against other rocks (leading to mechanical weathering).
