Question

3. Explain why the earth is just the right size. Why is the Earth's location in the solar system ideal for the development of complex life forms like humans?

4. How does the ocean remove carbon dioxide from the Earth's atmosphere? What role do tiny marine organisms play in the role removal of carbon dioxide? Why is this important to us?

Question 3

A planet's size assumes a significant job in whether it can "hang on" to its climate. Picture the planet as a major magnet pulling gases toward it – this is gravity. On the off chance that a planet is excessively little, similar to Mars, it won't have enough gravitational dismantle to have the option to clutch enough gases required for a tenable climate. Fortunate for us, earth not exclusively is the perfect size, yet in addition the perfect good ways from the Sun for its warmth and vitality to make a difference.Earth is the perfect size to make a gravitational power sufficiently able to counteract the perfect measure of gases from being discharged back to space and to develop, framing environmental conditions that can bolster life.

Earth has an entirely affable temperature and blend of synthetic substances that have made life conceivable here. Most strikingly, Earth is one of a kind in that the vast majority of our planet is canvassed in water, since the temperature permits fluid water to exist for broadened timeframes. Earth's huge seas gave a helpful spot to life to start about 3.8 billion years back. A portion of the highlights of our planet that make it incredible for continuing life are changing because of the continuous impacts of environmental change.

Question 4

The sea has a significant influence in the carbon cycle. In general, the sea is known as a carbon 'sink' since it takes up more carbon from the climate than it surrenders. Carbon dioxide from the climate breaks up in the surface waters of the sea. A portion of the carbon dioxide remains as broke down gas, however quite a bit of it gets transformed into different things. Photosynthesis by little marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Numerous creatures use carbon to make calcium carbonate, a structure material of shells and skeletons. Other concoction forms make calcium carbonate in the water. The spending of carbon by natural and concoction forms enables more carbon dioxide to enter the water from the air.

Living things in the sea move carbon from the air into surface dilutes then into the more profound sea and inevitably into rocks. This activity of life forms moving carbon one way is frequently called an organic siphon.

Carbon gets joined into marine life forms as natural issue or auxiliary calcium carbonate. At the point when life forms pass on, their dead cells, shells and different parts sink into profound water. Rot discharges carbon dioxide into this profound water. Take a gander at the carbon cycle intuitive to perceive how a lot of carbon is in the profound sea contrasted with different stores. Some material sinks right to the base, where it structures layers of carbon-rich residue. More than a great many years, synthetic and physical procedures may transform these residue into rocks. This piece of the carbon cycle can bolt up carbon for many years.
