It is thought that millions of comets rained down as ice on the early Earth and produced the oceans soon after it's creation 4,7000 million years ago. Look at the surfaces of Mercury and the Moon. They are covered in craters but, having no atmosphere and low surface gravity, the water leaked back out into space.

What is the abundance of selenium in atmosphere of earth?
The abundance of selenium in the atmosphere of Earth is very low, with concentrations typically ranging from 0.1 to 1 nanograms per cubic meter of air. Selenium is not a major component of Earth's atmosphere and is mainly found in soil, water, and food sources.
How common is cobalt?
Abundance of cobalt in the earth crust: 25-35 mg/kg Abundance of cobalt in the sea water: 0,02 microgram/L Abundance of cobalt in the solar system: 2,3.10-3 atom mole fraction relative to silicon=1. Abundance of cobalt in the human body: 0,000 002 1 %
Which makes earth suitable for life?
It's distance from the sun, its magnetic shield, it's abundance of liquid water. Take your pick.
Which planet has gasses land masses and large amounts of surface water?
Earth is the planet that has gases, land masses, and large amounts of surface water. It is the only known planet to have these three characteristics in such abundance.
How is water abundant?
Water is abundant on Earth primarily because of the water cycle, where water evaporates from oceans, lakes, and rivers, condenses into clouds, and falls back to the surface as precipitation. Additionally, the Earth's surface is about 71% covered by water in the form of oceans, which contribute significantly to the abundance of water on our planet.
Which planet has an abundance of liquid water?
Earth is the only planet in our solar system with an abundance of liquid water on its surface. Other planets may have water in the form of ice or vapor, but not in liquid form like Earth.
An abundance of what makes life possible on earth?
Air and liquid water.
Is uranium the element rare?
abundance of uranium in the earth crust; 2,5-3 ppm (mg/kg) abundance of uranium in the sea water: ca. 3 ppb (?g/kg)
Where is water found in abundance?
Water is found in abundance in the Earth's oceans, which cover about 71% of the planet's surface. Other sources of abundant water include glaciers, ice caps, rivers, lakes, and groundwater reserves. Additionally, water vapor in the atmosphere contributes to the global water cycle.
What is the most common solvent acting on the Earth's surface?
Water is the most common solvent acting on Earth's surface due to its abundance and ability to dissolve a wide variety of substances.
What is the abundance of selenium in atmosphere of earth?

Is radium rare or common?
Abundance of radium in the earth crust: 9.10-10 mg/kg Abundance of radium in the sea water: 8,9.10-14 mg/L
Which planet has gasses land masses and large amounts of surface water?
Earth is the planet that has gases, land masses, and large amounts of surface water. It is the only known planet to have these three characteristics in such abundance.
What is responsible for water on earth?
Water on Earth is primarily derived from comet impacts during the planet's formation, as well as volcanic outgassing. The water cycle, driven by evaporation, condensation, and precipitation, maintains the abundance of water on Earth. Additionally, the presence of oceans and polar ice caps contribute to the overall water supply on the planet.
