What molecule was not present 4 billion years ago?
A) No water molecules were present….
What molecules were 4 billion years ago?
Some 4 billion years ago, the Earth was largely covered by a huge ocean. This ocean contained a large number of small organic molecules, which are called “prebiotics” because they were there before life appeared.

How did Earth’s oceans form quizlet?
How did oceans form? All water on earth evaporated and turn into water vapor because it was too hot. Once the earth cooled, the water vapor began to condense to form rain. All the rain helped form the oceans.
How was the ocean formed 4 billion years ago?
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.

How did oceans form on Earth?
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
Who created Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
How did oceans develop on Earth?
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
How did the oceans become salty?
In the beginning, the primeval seas were probably only slightly salty. But over time, as rain fell to the Earth and ran over the land, breaking up rocks and transporting their minerals to the ocean, the ocean has become saltier.
How did the Earth looked 4 billion years ago?
Once upon a time, about 4.5 billion years ago, the Earth was an unformed doughnut of molten rock called a synestia — and the moon was hidden in the filling. That's one possible explanation for the moon's formation, anyway.
What created the oceans?
The ocean formed billions of years ago. Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
Who created the ocean?

What was the first ocean on Earth called?
Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).
What did God create on the first day?
light in On the first day, God created light in the darkness. On the second, He created the sky. Dry land and plants were created on the third day. On the fourth day, God created the sun, the moon and the stars.
What did God do before creating the world?
Nothing. Nothing. Since the world was created out of nothing (ex nihilo), nothingness prevailed. Therefore God was idling, just existing, perhaps contemplating creation.
Why does the ocean exist?
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
Did ocean or land come first?
Somewhere around 430 million years ago, plants and colonized the bare earth, creating a land rich in food and resources, while fish evolved from ancestral vertebrates in the sea. It was another 30 million years before those prehistoric fish crawled out of the water and began the evolutionary lineage we sit atop today.
Is peeing in the ocean OK?
Peeing in the ocean is totally fine, but don't pee in protected areas like reefs or smaller bodies of water, especially swimming pools.
Can you drink sea water if boiled?
Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).
What happened to the Earth 4 billion years ago?
Over time, the Earth cooled, causing the formation of a solid crust, and allowing liquid water on the surface. The Hadean eon represents the time before a reliable (fossil) record of life; it began with the formation of the planet and ended 4.0 billion years ago.
When did Earth’s water form?
3.8 billion years ago A sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago.
How did Earth get its oceans?
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
How did the ocean come to be?
Researchers think that the oceans formed as a result of a process known as “degassing.” When the earth was first formed, its temperature was well above the boiling point for water. Because of this, there was no liquid water on earth. Instead, all water was in the form of a gas.
How did Earth get oceans?
The ocean formed billions of years ago. Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
How old is the water you drink?
The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
Does Bible mention dinosaurs?
According to the Bible, dinosaurs must have been created by God on the sixth day of creation. Genesis 1:24 says, “And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.”
What came first dinosaurs or Adam and Eve?
Dinny's new owners, pointing to the Book of Genesis, contend that most dinosaurs arrived on Earth the same day as Adam and Eve, some 6,000 years ago, and later marched two by two onto Noah's Ark.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
