The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
<h3>What is the indirect evidence that helped us determine the layers?</h3>
Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.
The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.
So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
