Answer:

<em><u>an abandoned field, a cooling lava flow, a valley under a glacier, and an unused farm</u></em>

Explanation:

Primary succession happens in a place where there is no soil cover or it is removed.

an abandoned field- Secondary; because there is cover of soil left, even if vegetation is removed.  

a cooling lava flow- Primary; volcanic events lead to loss of soil layer, so this would lead to primary succession  

a valley under a glacier- Primary; retreating glaciers are lead to primary succession  

an unused farm-Secondary; the soil cover is still present

a burnt forest- Secondary; soil cover is still left for vegetation to start over again

a deserted mine- Primary; because there would be barren rocks left, so soil would be formed by pioneer species first.
