Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
Hydrologic Cycle The elements that combine to make water Hydrogen and oxygen are found in dust, grasses, and other stuff that formed Earth. The molten rock, called magma, which made up early Earth, contains water. Some water escaped from the magma and reaches the Atmosphere. As Earth cooled off, the water was able to settle on the surface and billions of liters later the oceans were formed. (5 points) |Score | | | 2.
Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide. By action of solar wind, molecules are blown away, forming a thin stream of hot gases continuously ejected from the solar corona. In case you do not know the meaning of a solar corona, it is the outermost atmosphere of the Sun. Amazingly, the thin streams of high gases move at a speed of approximately 400 kilometers (250 miles) per second (as cited in Yeomans 1991 p. 185). In addition, a comet frequently also displays smaller, curved tails composed of fine dust particles blown from the coma by the pressure of solar
The number of on any planet can be used to estimate how old the surface is. a. sunspots b. craters c. solar flares d. auroras 18. is only slightly smaller, less massive, and less dense than Earth is. a. Mercury b. Mars c. Venus d.
The EVA suits are the same with an added cooling garment that goes on over the long johns. It is like another pair of long johns with small plastic tubing woven all through it. Chilled water is circulated through it to get rid of body heat and solar heat. How near can an astronaut in a spaceship get to the sun before he or she gets burned? It depends on how well the spaceship is designed to handle the heat and light.
Why is it important? The oxygen in our atmosphere is important for breathing but also acts as a protection that shields us from harsh solar ultraviolet radiation. Much of this comes from another molecular form of oxygen, O(3), or
You can also wait until the last second and search for an extension cord and then plug it into your hair dryer so you can defrost your windshield with it. Cold weather can cause you to leave earlier as well because of the possibility of ice on the roads. Hot weather definitely has the advantage concerning having to leave earlier or having to prepare your vehicle to leave, because the only thing you might want to do, although not a necessity, is start your vehicle and crank up the air conditioning. Both types of weather often determine what kind of recreation is possible. For instance, snow man building doesn't quite work out in
One would be Fire Resistant Material which is chemically treated fabric and is used by every single one of our Fire Departments. Another is the Wind Monitor, the wind monitor allows for making high resolution measurements for a wind profile and for meteorological studies and predictions. NASA also developed Solar Energy. Solar Energy is a clean and efficient power source coming from the sun. Forest management was influenced by NASA as well, they use satellites to scan, monitor, and map radiation reflected and emitted by
There may be a small core of rock and perhaps ice at the center. This is surrounded by an ocean of liquid hydrogen and helium in the form of a metal. Above this is a layer of liquid hydrogen and helium, and above this a thick atmosphere. Jupiter is radiating energy, possibly as a result of radioactivity. The most famous feature is the Great Red Spot, which may be a huge storm in the atmosphere.
That's gravity- the force of attraction between all objects in the universe. 2 On Earth, it keeps people and objects from flying off into space. Gravity even keeps our air from floating off into space! An object's weight depends on the strength of the force of gravity. The pull of gravity is different on different bodies in space so weight varies on different planets or moons.
