Oceans and Seas

Oceans are the largest bodies of water that cover about 72 percent of the Earth's surface. Seas are large bodies of water that border the land and the oceans, and are sometimes lakes, which are landlocked seas.

Is Newfoundland affected by sea level rise?

User Avatar

Asked by Wiki User

Yes, Newfoundland is affected by sea level rise. The island of Newfoundland is surrounded by water, which makes it vulnerable to rising sea levels caused by climate change. This can lead to increased erosion, flooding, and other impacts on coastal communities in the region.

Can ambergris be found on US beaches?

User Avatar

Asked by Wiki User

Yes, ambergris has been found on US beaches, particularly along the Gulf Coast. It is a rare and valuable substance produced by sperm whales and is sometimes washed ashore after being expelled by the whale.

Where the Atlantic ocean is situated on equator?

User Avatar

Asked by Wiki User

The Atlantic Ocean is located both north and south of the equator, but it is widest near the equator at around the middle part of the ocean. The equator runs through the ocean near countries like Brazil, Gabon, and the Democratic Republic of the Congo.

The Indian Ocean is east of Africa. It is also home of the Madagascar Island. The Indian ocean is the 3rd largest ocean and is a huge producer of oil.

What is it called when the salt water flows inland from the ocean?

User Avatar

Asked by Wiki User

This process is called "saltwater intrusion." It occurs when saltwater moves into and contaminates freshwater sources, typically in coastal areas where there is excessive water extraction from wells or a decrease in freshwater flow.

What are the storm over the Indian ocean called?

User Avatar

Asked by Wiki User

The storms over the Indian Ocean are generally referred to as tropical cyclones. These storms can also be known as typhoons or hurricanes, depending on where they occur in the world.

What percentage of the biosphere are the oceans?

User Avatar

Asked by Wiki User

Approximately 71% of the Earth's surface is covered by oceans, which make up about 97% of the biosphere in terms of volume. Oceans are crucial for sustaining life on our planet and support a wide variety of organisms.

What is the rise and fall of sea level that happens twice a day?

User Avatar

Asked by Wiki User

The rise and fall of sea level that happens twice a day is called the tidal cycle. This cycle is caused by the gravitational pull of the moon and the sun on the Earth's oceans, creating high and low tides approximately every 12 hours.

What percentage of the Earth's surface is covered by lakes and rivers?

User Avatar

Asked by Wiki User

About 3% of the earths water is freshwater, most of it in pack ice, glaciers, and aquifers. Only about one-third percent is found in rivers and lakes. The largest freshwater lake by volume is Lake Baikal in Russia.

What seas run through the equator?

User Avatar

Asked by Wiki User

The South China Sea, the Philippine Sea, and the Java Sea all run through the equator.

Why are oceans important to weather patterns?

User Avatar

Asked by Wiki User

Oceans play a critical role in regulating Earth's climate by absorbing and releasing heat, influencing atmospheric circulation patterns, and providing moisture for precipitation. The transfer of heat and moisture from the oceans to the atmosphere helps drive weather patterns and climate systems around the world.

Are the population of small photosynthetic organisms found near the surface of the ocean?

User Avatar

Asked by Wiki User

Yes, small photosynthetic organisms like phytoplankton are commonly found near the surface of the ocean where they can access sunlight for photosynthesis. These organisms form the base of the marine food chain and play a crucial role in marine ecosystems.

What causes melting at mid-ocean ridges?

User Avatar

Asked by Wiki User

Melting at mid-ocean ridges is primarily caused by the upwelling of hot mantle rocks. As the mantle rises towards the surface due to tectonic forces, the decrease in pressure lowers the melting point of the rocks, leading to the formation of magma. This magma eventually solidifies to form new oceanic crust.

How does the warming of the worlds oceans flow of the water cycle?

User Avatar

Asked by Wiki User

The warming of the world's oceans can intensify the water cycle by increasing evaporation rates, leading to more water vapor in the atmosphere. This can result in more frequent and severe weather events like storms and heavy rainfall. Additionally, warmer ocean temperatures can impact ocean currents, which play a significant role in distributing heat around the globe.

Are the mid Atlantic ridge and the east pacific ridge moving apart?

User Avatar

Asked by Wiki User

Yes, both the Mid-Atlantic Ridge and the East Pacific Rise are divergent boundaries where tectonic plates are moving apart. This movement results in the creation of new oceanic crust as magma rises from the mantle and solidifies at the spreading center.

How did scientists discover that rocks farther away from the mid ocean ridge were older than the ones closer to the mid ocean ridge?

User Avatar

Asked by Wiki User

Scientists discovered that rocks farther away from the mid-ocean ridge were older than those closer to it through radiometric dating of the rocks. By analyzing the age of the rocks using isotopes with known half-lives, they were able to determine that the rocks get progressively older as you move away from the ridge due to the process of seafloor spreading.

Do lakes and rivers have more freshwater than ground water?

User Avatar

Asked by Wiki User

Dal Lake isn’t just a body of water; it’s a lifeline for the people of Srinagar. Summer transforms it into a vibrant hub with houseboats and Shikaras (traditional wooden boats) gliding gracefully. The morning market on the lake is a photographer’s dream, offering a unique shopping experience with vendors selling everything from fresh produce to exquisite handicrafts.

Do tsunamis in the Atlantic Ocean come to New Jersey?

User Avatar

Asked by Wiki User

While tsunamis are possible in the Atlantic Ocean, they are not common in the region of New Jersey. The likelihood of a tsunami hitting a specific area is dependent on factors such as the location of fault lines and undersea geology, which are not as conducive to tsunami generation in the Atlantic along the New Jersey coast compared to regions like the Pacific Ocean.

What motion of the sea floor is responsible for the formation of the mid ridge Atlantic ridge's rift valley?

User Avatar

Asked by Wiki User

The sea floor motion responsible for the formation of the Mid-Atlantic Ridge's rift valley is divergent plate boundary movement. As two tectonic plates move apart, magma rises to fill the gap, creating new oceanic crust. This process forms the rift valley along the center of the Mid-Atlantic Ridge.

What is occurring along the mid- atlantic ridge?

User Avatar

Asked by Wiki User

The Mid-Atlantic Ridge is a divergent boundary where tectonic plates are moving apart. As the plates separate, magma rises to fill the gap, creating new oceanic crust. This process leads to the formation of new seafloor, volcanic activity, and earthquakes along the ridge.

Is the underlying rock beneath the ocean floor silica?

User Avatar

Asked by Wiki User

The underlying rock beneath the ocean floor is primarily basalt, which is a mafic rock rich in iron and magnesium. Silica-rich rocks like granite are typically found in continental crust, not beneath the ocean floor.

How does green house rise the sea levels?

User Avatar

Asked by Wiki User

Greenhouse gases trap heat in the Earth's atmosphere, causing global temperatures to rise. As a result, ice caps and glaciers melt, contributing to the overall rise in sea levels. This is because the melted ice adds more water to the oceans, leading to an increase in sea level.

Which of these are fissures through which water and water vapor escape from the Earth's surface?

User Avatar

Asked by Wiki User

Fumaroles, hot springs, and geysers are fissures through which water and water vapor escape from the Earth's surface. These geological features are commonly associated with areas of volcanic activity where magma heats underground water, causing it to rise and escape through the fissures.
