How deep is the ocean on Mars?
Prior work found Mars was once wet enough to cover its entire surface with an ocean of water about 330 to 4,920 feet (100 to 1,500 meters) deep, containing about half as much water as Earth’s Atlantic Ocean, NASA said in a statement.

Why did Mars lose its water?
Based on data gathered by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN), scientists suggest that dust storms rising from the Martian surface appear to have been slowly sucking away the planet’s water over the course of millions of years, sweeping water molecules up on a wild journey into the atmosphere.
Does Mars have ocean?
New 3D climate simulations of the planet’s ancient atmosphere and water suggest a liquid ocean once existed in the northern lowland basin of Mars. This ocean potentially persisted even when average global surface temperatures were below the freezing point of water, the peer-reviewed work suggests.
Is there ice on Mars?
Ice is also very common on Mars, not only at the polar caps, but below the surface in many locations on the planet. The new paper explained: There is widespread evidence of water ice on Mars, with numerous locations where it is currently exposed at the surface.
What is underground in Mars?
Liquid water on Mars is likely to exist underground, at depths where ice is melted by warmth from the planet’s interior. In caves, the temperature stays relatively stable, so they would also offer refuge from the 200-degree Fahrenheit day-night swings on the surface.
What is the average depth of Indian Ocean?
Indian Ocean is the third largest ocean in the world, and it covers 1/5th of the total ocean area. It holds 20% of the total water in the world. It has an average depth of 3,960 meters or 12,990 feet. The deepest point is at 7,450 meters or 24,442 feet. The mighty Indian Ocean has a number of surprises hidden in it.
Is there an undiscovered land mass in the Indian Ocean?
Scientists are now calling this undiscovered land mass “Mauritia.” The Indian Ocean’s deepest point is the Sunda Deep, which is located in the Java Trench near the southern part of Java, Indonesia. It has a maximum depth of 25,344 ft.
What are 5 interesting facts about the Indian Ocean?
Interesting Facts About the Indian Ocean The Indian Ocean has a total area of 73,440,000 square kilometers or 28,360,000 square miles. Its size makes the Indian Ocean the third largest body of water in the world. Recently, scientists have found a “lost continent” whose remains are thought to exist in the depths of the Indian Ocean.
Is the Indian Ocean the smallest ocean in the world?
Indian Ocean, body of salt water covering approximately one-fifth of the total ocean area of the world. It is the smallest, geologically youngest, and physically most complex of the world’s three major oceans (Pacific, Atlantic, and Indian).
