What is the difference between lava and magma?
Magma is composed of molten rock and is store in the earth’s crust. Lava is magma that reaches the surface of our planet through a volcano vent
300
What are the 3 main categories on the periodic table?
Non- metals, metals and metalloids
400
What is the difference between a chemical and a physical change?
A physical change is a change in which no new substance is formed, where a chemical change results in the formation of one or more new substance.
400
The environment is made up of 2 factors, list them and define them.
Biotic factors, which are all living organisms inhabiting the earth.
Abiotic factors- nonliving parts of the environment (i.e. temperature, soil, light)
400
What did we cook when looking at transformation of energy?
popcorn
400
Process of a conglomerate rock. Explain in detail.
The process happens when sedimentary rocks join together to make up of large rock. This physical occur when strong water currents transport the different shape particles together.

Explain what the ecosystem is in great detail.
An ecosystem includes all the abiotic factors in addition to the community of biotic things that exists in a certain area. Some ideas associated with an ecosystem are energy flow, and the cycling of nutrients and wastes among the various biotic and abiotic components.
500
What is the energy equation for burning chemical?
potential-> friction-> chemical-> heat -> light
500
how is sedimentary rock formed. explain in great detail
it is formed in 4 main ways: by the deposition of the weathered remains of other rocks, by the accumulation and consolidation of sediments, by the deposition of the results of biogenic activity and by precipitation from solution
