Answer: 1. recollapsing universe
4. critical universe
3. coasting universe
2. accelerating universe
Explanation:
The universe is continually growing and galaxies are moving apart relative to one another.
These four models foresee the expansion and possible contraction of the universe.
Recollapsing universe: this model predicts that galaxies will stop growing apart and start getting closer to one another. It predicts that there is enough density to stop the growth of the universe in the future.
Critical universe: the universe has the same density as the critical density. This is the difference between the density the universe requires to stop and that of a universe with too little density to ever stop expanding
.
Coasting universe: has enough density to enable galaxies to keep growing apart
, in essence, less than the critical density.
Accelerating universe: this model explains that the distance of far-off galaxies is growing exponentially from an observer over time.
Answer:
Catastrophism.
Explanation:
According to Geology, there's a theory which held that surface, mountains, lakes, were created by suddenly because of great catastrophes like earthquakes and floods.

Answer:
The answer is below
Explanation:
a) Lily has 24 chocolate chip cookies and 32 vanilla wafers, since she has to put the chocolate and vanilla in the same bag, the number of bags must be a factor of 24 and 32. Below the bags are listed:
Number of bags: 1 2 4 8
Number of cookies: 24 12 6 3
Number of wafers 32 16 8 4
This means that the largest number of bag is 8 which would contain 3 cookies and 4 wafers
b) For the chocolate chip to be placed, the number of bags must be a factor of 24. It is given below:
Number of bags: 1 2 3 4 6 8 24
Number of cookies: 24 12 8 6 4 3 1
c) For the vanilla wafers to be placed, the number of bags must be a factor of 32. It is given below:
Number of bags: 1 2 4 8 16 32
Number of wafers: 32 16 6 4 2 1
