Definition
Gravity exerts a downward force on all mass. On land, this force requires animals to have robust skeletal structures to support their body weight, limiting how large they can grow.
Why it matters (in Poovi’s context)
Explains why the largest terrestrial animals (like dinosaurs) were significantly smaller than the largest marine animals (like blue whales), as water’s support mitigates gravitational effects.
Key properties or components
- Pulls mass downwards
- Requires structural support
