Why does the Earth have more water than land?
It has to do with the different kinds of rocks in the Earth's crust: continents are made of granite, and ocean crust is made of basalt. The more granite there is, the more continent there is, and the more of the Earth's surface rises above the ocean basins. Water fills the basins. Right now, there is more basin than continent, and so more ocean surface than land surface.Answer 2:The surface of the Earth is covered about 70% by water and it may seem like most of Earth is composed of water, but actually it's a much smaller amount of water compared to the rocky planet - about 0.5% of the whole entire planet is water.Answer 3:Water is the most important resource on Earth, and more importantly it sustains life. Although 75% of Earth is covered in water, Earth is mostly made of rock. In terms of weight, only 0.5% of Earth's weight is water. It looks like there is more water because water pools in low and deep basins, like lakes, streams, and oceans.
What is bigger land or water??
Well, "land", refers to what's above the surface of the water. It includes many elements and minerals. Water on the other hand only includes H20. The Oceans cover 70% of the earth. The core of the earth is molten rock, hence liquid. So you could call it a rock ocean (it does have currents). Furthermore, there is much moisture (gaseous water) in the atmosphere which covers 100% of the earth, as well as ice on the polar caps (while it last). That counts as land and water. So you kinda comparing apples and pie. But most known matter in the universe is plasma, like the sun. Some planets have much more amazing oceans, like the moons of Jupiter and Saturn. But here's how much water there is: About 1,460 teratonnes (Tt) (1 360 000 000 km³ ) of water covers 71% of the Earth's surface, mostly in oceans and other large water bodies, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds As for the Earth, here is the best I could find: The mass of the Earth is approximately 5.98×1024 kg. It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%); with the remaining 1.2% consisting of trace amounts of other elements. Due to mass segregation, the core region is believed to be primarily composed of iron (88.8%), with smaller amounts of nickel (5.8%), sulfur (4.5%), and less than 1% trace elements. SO THE EARTH IS MOSTLY IRON...and that's mostly at the core. Saltwater oceans hold 97% of surface water, glaciers and polar ice caps 2.4%, and other land surface water such as rivers and lakes 0.6% Much of the universe's water may be produced as a byproduct of star formation. Water vapor is on: Mercury - 3.4% in the atmosphere Venus - 0.002% in the atmosphere Earth - trace in the atmosphere (varies with climate) Mars - 0.03% in the atmosphere Jupiter - 0.0004% in the atmosphere Saturn - in ices only Enceladus (moon of Saturn) - 91% in the atmosphere Water ice is on: Earth - mainly on ice sheets polar ice caps on Mars Titan Europa Enceladus
What cools off faster land or water and why?
Land cools quicker and heats up quicker. In general liquids take much longer than solids to change temperature. Think of this, when you are washing up, the bowl of water takes ages to cool back down to room temp, but the solid plates heat up to water temp very quickly, then cool back down as soon as they are out of water.
Is water heavier than land?
Earth (or land) is more dense than water and will weigh more. The average density of the Earth as a whole is over 5 times the density of water.
Why does land cool off faster than water?
The water has more "thermal mass." It is slower to heat and cool than the land. Result is that water keeps the surrounding areas cooler when it is hot and warmer when it is cool. Some people use this effect to save energy by putting a few 2L pop bottles full of water in the refrigerator if there is a lot of empty space. Once the water bottles are cold, they keep the frig temperature more stable when you are opening and closing the door. Aloha
Why does my turtle like water more than land?
Your turtle is semi-aquatic, so staying in the water 24/7 says what? What is "just a baby"? And getting stuck to an intake tube for a filter is NOT an on purpose thing! The poor panicked darlin! IF you got sucked unwater to something, do you think you would break free? Would YOU like IT? How large is this tank? How powerful is the pump, and how big is this 'baby'? How long have you had him, and how is his habitat set up? Let's put you in the water... no land in sight, and the only thing you can grab MOVES when you touch it. Would YOU be secure? Would YOU call that 'land?' Is this a very tired baby who has deep water with currents, and no plants to rest on, since the island stresses him? What is the water temp., and the basking temp over this floating mass, and how do you keep the floating mass heated? Where is he basking to get his UVB, as it moves around the tank and stays at least 10 degrees warmer? All this sounds like husbandry to me. http://www.redearslider.com/index_habita... If you are talking about an infant turtle (1-3") with moving land, in a tank which sucks him to the uptake tube?... He has no warm safe place to bask? It sounds like you are caring, but not informed. And your baby is not happy. I know you want to do what is best for your turtle. You can either email me at oxo_sensual_oxo@yahoo.com or read all the links I'll post. He needs heat for basking and a set water temp (for health and digestion), and a UVB souce. He needs a way to be under the UVB, and not floating all over the place... http://www.uvguide.co.uk/ A content turtle will bask nearly 1/3 the day. Without seeing your setup, your troubles could be any number of things. Read the sites, or email me with further details. Too cool temps. will quickly lead to respiratory problems. I'm sorry I couldn't be of more help.
Why are ocean animals so much bigger than land animals?
RE: Why are ocean animals so much bigger than land animals?The largest ocean going animals are larger than any land animals that ever lived because the buoyancy of an aquatic animal allows its weight to be efficiently dispersed. The weight of an animal as large as a whale would make it impossible to survive out of the water.The weight of its own body would not allow it to inflate its own lungs.
Is there more water than land on earth?
Yes and no.Yes: About 70 percent of the earth's surface is normally covered by water.No: The Earth's solid components are many times larger than the small amount of water (liquid, ice, fresh water, salt water) on Earth. In this illustration, you can see the tiny (!) ~860-mile diameter sphere that all the Earth's water comprises, compared to the Earth.Image: US Geological Survey; Illustration by Jack Cook, Woods Hole Oceanographic Institution.
Why is the air pressure greater under water than it is on land?
Technically, under water it's not "air pressure" but indeed "water pressure". The reason why the pressure under water is greater than the pressure on land is that the pressure one experiences at any place on Earth is simply the weight of all of the planet that's above oneself. On land, this is a column of air that weighs approximately 14 pounds per square inch (at least at sea level; at higher altitudes it's lower). Under water, that whole column of air is still there, and added to that is a column of water that weighs about 0.43 pounds per foot. At only 30 feet, the weight of the water is as much as all the air above it, and the pressure only goes up from there.
Why does land heat and cool faster than water?
Here’s a simple attempt at an explanation.You need to understand that at similar conditions, land and water actually receive the same amount of heat. It’s just how much heat is needed to raise the temperature/hotness of the item.It’s because of heat capacity. Heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree Kelvin, but intuitively it means how much heat energy you have to “pay up” in order to increase the temperature(or hotness) of a particular substance.Water is great at “storing heat”, because it takes a lot of heat energy to actually heat it as compared to say metal and sand.The opposite applies the same way too. Water cools down slower than land even if they release energy at the same rate.
