The main difference between geography and geology
is that geography is mostly dealing with the physical overall shapes of
the land. Geology is a science that is interested in how the land got
into the shape it did.
Geology is mostly about what the ground is
made up of from a natural perspective. What kind of rocks it contains
and how those rocks or layers of rocks got there.
Geography is
mostly dealing with mapping the extent of landforms, how far rivers are,
how long mountain ranges are, how long the coast line is. This is often
from the perspective of people or culture.
Alluvial fan could be the answer. Alluvial fans are cone shaped deposits of sedimentary particles. The particles can be sand. silt, gravel or clay. These land-forms are formed at the mouth of canyons or in valleys where ephemeral streams can occasionally transport material to the mouth of the canyons. An ephemeral stream is one that is created after a shower of rain or other form of precipitation; they are not permanent streams. <span />

The statement that is not true is: A healthy ecosystem can support an unlimited number of life forms.
Any ecosystem has its limits. No matter is a healthy, in perfect shape, and very large ecosystem, there's always a limit as to how much life forms can the ecosystem support. If the number of life forms surpasses the ability of the ecosystem to support them, than the ecosystem will crash, be destroyed, and experience a lot of changes, with the death of lot of life forms involved in the process as well.
There isn't such thing as an ecosystem that has the ability to support an infinite number of life forms, there's only ecosystems that are able to support limited number of life forms.
At the bottom of the food chain, green phytoplankton is eaten by krill and shrimp. The krill and shrimp are later eaten by squid, whales, and fish. Later, seals, penguins and birds eat the squid. Finally, killer whales/orca eat squid as well.
