Which of the following is the first step in primary succession?

Question

1. Lava cools to form an area of rock.

2. Water begins to fill the cracks of the new rock.

3. Soil covers the rocks as life begins to die and decompose.

4. Rock weathers and sediment begins to collect in the cracks of rocks.

Answer 1

Primary succession is when there is a brand new area formed where no life has previously been.  When new land is created by lava froma volcanic erruption, it is barren.  

So, in your example, the order of events would be: 1, 2, 4, 3.  However, the first stage in succession is generally considered when the first life takes hold, for example, when you see the first pioneer species like a lichen.  Therefore, I'm not sure what the writer of the question is looking for because I don't really see a correct answer.  While #1 is the first thing to occur, it's not really the beginning of succession until life shows up.  #3 mentions life decomposing, but life hasn't begun yet in 1, 2, or 4.

Answer 2

you kinda almost put them in order its 1
