Sentences with phrase «dense than the atmosphere»

Any additional heat in the atmosphere, therefore, will tend to radiate out into space (an infinite heat - sink) or into the oceans (which, being 1000 times denser than the atmosphere and having an enormous volume, are a near - infinite heat - sink).

Not exact matches

Although the gas is at a chilly minus 63 degrees Fahrenheit (minus 53 degrees Celsius) and is 300 trillion times less dense than Earth's atmosphere, it's still five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way.

Titan's atmosphere is far denser than Earth's, its gravity just one - seventh as strong, and its average temperature a chilly — 289 degrees Fahrenheit.

So another model, proposed in 2015, assumes the impact was extremely violent, so violent that the impactor and Earth's mantle vaporized and mixed together to form a dense melt / vapor mantle atmosphere that expanded to fill a space more than 500 times bigger than today's Earth.

Akatsuki's 2 - year mission aims to peel away some of the mystery of Venus's dense, cloudy atmosphere, which sweeps over the planet at speeds exceeding 300 kilometers per hour, or 60 times faster than Venus itself rotates.

At another extreme, Saturn's giant moon Titan seems more like a planet in its own right, larger than Mercury and cloaked in a dense atmosphere.

Microclimate is the climate near the ground which can be colder or warmer than in the free atmosphere, depending on local topography (e.g. north vs. south side of a hill, higher vs. lower elevation) and vegetation (e.g. young sparse vs. old dense forest).

Using diamond anvil cells (DAC), the team applied 2.5 GPa of pressure (25 thousand atmospheres) to pre-compress water into the room - temperature ice VII, a cubic crystalline form that is different from «ice - cube» hexagonal ice, in addition to being 60 percent denser than water at ambient pressure and temperature.

Using climate models at the Laboratoire de Météorologie Dynamique, François Forget (CNRS) and Martin Turbet (UPMC) show that, with a cold climate and an atmosphere denser than it is today, ice accumulated at around latitude 25 ° S, in regions corresponding to the sources of now dry river beds.

And while Martian winds can kick up sky - blotting dust storms like those that plagued the Spirit and Opportunity rovers this summer, the atmosphere of Mars is 100 times less dense than that of Earth.

Although the difference in altitude doesn't sound much, the differences between the inner and outer atmosphere are actually quite pronounced, with the atmosphere 10 times denser at 125 km than it is as 150 km.

Upon your arrival to the second planet from the sun, you'd be greeted by surface temperatures comparable to those in a pizza oven, and a carbon - dioxide atmosphere more than 90 times denser than ours here on Earth.

TRAPPIST - 1b, the innermost planet, and TRAPPIST - 1c likely have rocky interiors and atmospheres denser than Earth's, according to the study.

Coronal holes are gaps in the Sun's outermost atmosphere which are less dense and cooler than their surroundings.

This orbits places the planet near the inner edge of its host star's habitable zone, where liquid water could exist in liquid form under favorable conditions such as an albedo of 0.52 with an orbital eccentricity of 0.11 and more than 52 percent cloud cover under a sufficiently dense atmosphere of water, carbon dioxide, and molecular nitrogen like Earth's (ESO science release; Pepe et al, 2011; and Kaltenegger et al, 2011 — more below).

Venus has a much higher albedo (reflectivity) than Earth because of its thick cloud cover (and would even have a high albedo without the clouds due to Rayleigh scattering from the dense CO2 atmosphere).

simply put — planets with thick (denser) atmospheres are warmer than ones with thinner atmospheres — independent of the constituent gases in the atmosphere!

While partially deforested areas exhibited a less unstable atmosphere than the neighbouring dense forest, the team found that shallow clouds formed over them.

A stronger gravitational field will produce a lower, denser, warmer surface than a weaker gravitational field since the amount of solar energy retained by the atmosphere will be focused into a smaller volume and that amount of energy will be determined by the amount of mass available to absorb it at any given level of solar irradiation.

The atmosphere of Venus is very dense so the surface is much hotter than it otherwise would be.

Their model was based on the observation that in the troposphere (the lower and denser layer of the atmosphere, with pressures greater than 0.2 atm) the heat transfer is mostly by convection and the temperature distribution is close to adiabatic.

In the heavier denser liquid water of the ocean transit is slowed down even further, some fourteen times more than in our atmosphere, as water being a transparent medium for visible light transmits it through unchanged but delays it in each encounter as it tries to absorb it but can't.

Mars: thin atmosphere (albeit composed of 95 % CO2)-- > no «greenhouse effect» Earth: denser atmosphere — > some real «atmospheric effect» Venus: 95x denser atmosphere than on Earth — > powerful «atmospheric effect» No atmosphere — no «greenhouse effect»

At low altitude and high temperatures (greater than 30 °C or 86 °F), over the ocean, it can reach 4.3 % or more of the atmosphere and is less dense than dry air, causing it to rise.

And so today we have a carbon dioxide atmosphere on Venus which is 92 times more dense than Earth's atmosphere at the surface.

Factor in the fact that soils amd water are at least ~ 1000 times more dense than air and the idea that gases can heat warmer surfaces like soils and especially water whilst most of the atmosphere is actually much colder just seems - well — ludicrous.

It is lucky that it is denser than air, if not then all the methane generated near the surface of the terrasphere would whisk its way off into the atmosphere.

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

So isn't the whole issue really revolving around how dense the atmosphere is at any given time and has atmosphere during the latest warm spell been denser than say in the 1970s during that cold spell?

There is clearly a lot of atmosphere above the effective radiating height albeit much less dense than the troposphere.

However, if we add the solar wind and moon slow stipping of the atmosphere, which show that atmosphere must have been denser in the past than now, a simpler and more logical explaination, that the giant flying critters could fly due to the denser atmosphere then extant, is warrented.

This, plus some stripping away from the gravitational effects of the moon, strongly suggests that the atmosphere formerly used to be denser than it is now.

Bionic leaves that could produce energy - dense fuels from nothing more than sunlight, water and atmosphere - warming carbon dioxide, with no byproducts other than oxygen, represent an ideal alternative to fossil fuels but also pose numerous scientific challenges.

This means that it takes longer for it to lose that heat (cool) than the less dense atmosphere at higher altitudes.
