How long nautilus been alive on earth?
Nautilus species have existed for around 500 million years, making them some of the oldest surviving lineages of marine organisms. They are often referred to as "living fossils" due to their ancient lineage and relatively unchanged morphology over millions of years. These creatures have survived several mass extinctions, adapting to various environmental changes throughout Earth's history.
What is an offshore deposit of sand situated parallel to the coast called?
That is known as a barrier island. It provides protection to the mainland from storm surge and erosion.
What substance found in sea water comes from land?
sand and just about everything else in it has been dissolved from rocks or is suspended in it in very small yet visible particles
How does climate affect the oceans?
itm has ice in it which causes the sea to cool down so it turns the air colder, so the rain is colder which makes everything it lands on colder :)
hope this helpped geo dude!
What is the sunlight zone also known as?
The sunlight zone contains most of the oceans' plants and animal life. This zone extends from 5 to 300 feet. It is also called the euphotic zone.
What are North Carolina's two major ocean ports?
North Carolina's two major ocean ports are the Port of Wilmington and the Port of Morehead City. The Port of Wilmington is known for its diverse cargo operations, including containerized goods, while the Port of Morehead City primarily handles bulk commodities and is vital for the state's fishing and seafood industries. Both ports play a significant role in facilitating trade and supporting the local economy.
A photophore is a light-emitting organ commonly found in animals such as fireflies and bioluminescent deep sea fish.
Why does water in a bowl shaped drainage basin not eventually flow to the ocean?
Because the water may collect at the bottom of the basin, or evaporate.
The Atlantic and Pacific Oceans would be one Ocean and the whole global oceanic gyres would alter to accommodate.
What is the third layer of the ocean?
The third layer of the ocean is the Bathypelagic Zone. This is also called the dark zone. There is no sunlight in this zone, and it extends from 1,000 meters to about 4,000 meters in depth. The pressure is extremely high in this zone.
The layer of the ocean extending from the base of the thermocline to the bottom is called the deep zone or deep ocean zone. This region is characterized by consistently cold temperatures and limited sunlight penetration, which affects the marine life and ecosystems found there.
1. Outer space contains virtually no gas/dust to scatter light.
Outer space is black.
2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective.
3. If the sky's colour was due to reflection from the oceans, then it would be white above Antarctica, which is snowy white.
4. If the ocean was blue because it reflects the sky, why does it still look blue-ish when under a totally clouded-over sky?
5. Why blue? Light scattering by the atmosphere (Rayleigh scattering) has most effect on the most energetic light. The most energetic light is that with the highest frequency/shortest wavelength.
6. So, while all light is scattered, blue light is scattered the most, so the atmosphere "captures" more of the blue light, letting more of the red light through, and the atmosphere is coloured blue by that "captured" light.
7. If there were *no* selective scattering, and all wavelengths were scattered *equally*, the sky would appear white.
What does phytoplankon refer to?
They are microscopic marine plants that are the beginning of the food chain in the ocean.
The periodic variation in the surface level of the oceans and of bays, gulfs, inlets, and estuaries, caused by gravitational attraction of the moon and sun.
