You will need two apple trees, but for best fruit production you should use two different varieties (see pollinization chart at http://www.acnursery.com/apple_pollinizer.pdf).
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
Yes, snow apple and Cox Orange Pippin are compatible for cross-pollination. Both are apple varieties with overlapping bloom times and can help each other with pollination to produce fruit. Bees and other pollinators can transfer pollen between the two varieties effectively.
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
Self pollination is when a flower pollinates itself with its own pollen and cross pollination is when a flower uses another flower's pollen.

Cross pollination is when the wind or a insect carries pollen from one flower to another. Self pollination is when a flower produces pollen and uses it in asexual reproduction.
Cross pollination happens when the pollen of one flower is placed upon the stigma of another flower, whether of the same varietyor not.
This transferring process is called pollination.
pollination; if it from the same plant (self-fertilization; self-pollination); pollen from one plant to the stigma of another plant (cross-pollination; cross-fertilization)
cross fertilization
Pollination
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
