What is a mile? What is a garden habitat? What factors determine height? What is the density of the stratosphere? How big was the biggest titanosaur? How many kinds of ceratopsians were there? What is the air pressure in the stratosphere?
After an hour, the balloon has ascended to almost 100,000 feet (30,480 meters). This is the stratosphere, the second-to-last atmospheric layer before outer space. Below, the Earth's features are obscured by a thick layer of cloud. Above, the blue sky has faded to dark black. It's ...
Place plant in the hole so the top of the root ball is level with the surrounding soil. Fill in soil around the root ball, gently tamp down, and water well to remove air pockets. Space plants 2 to 3 feet apart.GAURA CAREContainer with Stratosphere™ White gaura, Superbells® ...
you'll be able to see stars down to the horizon but no farther (because Earth is in your way). But if you travel up — say, to the top of a mountain — you get a better vantage point and can see stars farther down than you could before. ...
Some scientists predict that nuclear winter would be followed by an even harsher spring. They theorize that the sunlight bounced back up from the smokecloudswould heat up nitrogen oxides in the stratosphere. At high temperatures, the nitrogen oxides, which formed due to blast-burned oxygen, would...
As climate change stokes larger and more intense wildfires, firestorms are likely to become more common. Here’s why they occur and what makes them so dangerous.
NOAA’s Office of Atmospheric Research found that space traffic, which is projected to increase in the future, could boost emissions of soot directly into the stratosphere, which could deplete the ozone layer in some seasons. “We need to learn more about the potential impact of hydroc...
NEW YORK (AP) — There's only one Roxie Hart. And yet — stay with us here — there aremany Roxie Harts. The murderous, washed-up chorus girl is the beating, biting heart of Broadway's mainstay musical “Chicago,” but no single actor owns her....
The Earth's atmosphere is divided into five distinct layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has distinctive qualities and is crucial in regulating the climate of the Earth and protecting life ...
The proton-to-electron ratio is always one to one, so the atom has a neutral charge. For example, a carbon atom has six protons and six electrons. It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the...
