Answer:
A medida que la Tierra se enfrió, se formó una atmósfera principalmente a partir de gases arrojados por los volcanes. Incluía sulfuro de hidrógeno, metano y de diez a 200 veces más dióxido de carbono que la atmósfera actual. Después de aproximadamente 500 millones de años, la superficie de la Tierra se enfrió y solidificó lo suficiente como para que el agua se acumulara en ella.

During a heavy thunderstorm, most likely, surface runoff would be in areas that has sloping landscape. Since at these times, these surfaces would be saturated with water causing for not absorbing water into the soil so it would slope down running off to streams. This is one of the reasons of having landslides.

See the answer below
Explanation:
Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.
<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>
