Em pleno verão o cume da montanha mais próximo do sol em relação ao nível do mar está coberto de neve explique como isso é possível

Translated =

In midsummer the summit of the mountain closest to the sun in relation to the level of the sea is covered with snow explain how this is possible

Because temperature levels are dropping and the more cold it became it slowly started freezing up and even though the sun was there it built up and became snow.
