Volcanic eruptions and comets both contributed to bringing water and other gases to Earth's surface creating the atmosphere. Volcanic products created nutrient rich soils for plants to grow and if the comets were large enough, they could create large enough indentations for lakes and oceans to form.

Where did Earth's water come from?

Most likely from Comets from the Ort cloud (actually comets may have been prevalent throughout the Solar System early on then relegated to the Ort cloud by the solar wind) smashing into earth during its development. But you can't discount Volcanic action either. TommyTrouble

Were there only volcanoes in the beginning of Earth?

No. Earth has had volcanoes through its entire history. Even in modern times there are several dozen volcanic eruptions every year. However, Earth saw much more volcanic activity in it early years than it does today, as the interior of the planet was hotter.

How did climate change kill all the dinosaurs?

It is not certain that climate change killed the dinosaurs. It is likely that several factors combined. Temperatures though rose by around 10°C between the Early and Middle Cretacious Period. This could have been caused by a huge asteroid impact. It could also have been caused by extreme volcanic eruptions in the area of India and Pakistan. There was great climate change in the Late Cretacious Period. Continental movement and volcanic eruptions made many changes. Sea levels fell and tropical vegetation was replaced by woodlands. If the vegetarian dinosaurs' food supply failed, then the food chain would affect the meat eaters too.
