Ethan is the significance of volcanoes for habilitation of earth?
Released gas that helped build the atmosphere
What is the significance of plate tectonics?
Possibility for climate stability.
What shield the earth from particle from the sun
Ye magnetic field
What are the 3 types of elements?

Iron
What are the six defining factors for life as we know it?
- order

- growth and development
- energy utilization
- response to the environment
- evolutionary adaptation

It is significant because it could be first start to the beginning of life- it is a simple way of storing amino acids.
What is the role of clay in the formation of life.
