What happens when a comets dust particles enter our atmosphere?
When a comet's dust particles enter our atmosphere, they create bright streaks of light known as meteors or shooting stars. Friction with the atmosphere heats up the particles, causing them to vaporize and produce a glowing trail as they streak across the sky.
How do radiation reradiation conduction and convection work together to heat the atmosphere?
Radiation from the Sun warms the Earth's surface, which then emits infrared radiation towards the atmosphere. This infrared radiation can be absorbed by greenhouse gases and clouds, leading to reradiation back towards the Earth, trapping heat. Conduction and convection transfer this heat within the atmosphere, redistributing it vertically and horizontally to maintain Earth's temperature balance.
What layer do airplanes sometimes travel to avoid bed weather?
Airplanes sometimes travel to the jet stream layer to avoid bad weather. The jet stream can provide a smoother ride above turbulent weather systems such as thunderstorms. It is located at high altitudes, typically between 30,000 and 40,000 feet.
Natural greenhouse effect is good because it keeps the Earth warm and habitable using natural greenhouse gases in the atmosphere. Although when there is a "build-up" of these gases, the sun's energy (from sunlight) is trapped between the atmosphere and Earth's surface allowing energy to enter but making it extremely difficult to get out. Thus resulting in a warmer than normal Earth.
What benefits to human life are provided by earth's atmosphere?
What is the largest reservoir of nitrogen and water vapor?
The largest reservoir of nitrogen is the Earth's atmosphere, where it makes up about 78% of the air we breathe. The largest reservoir of water vapor is also the Earth's atmosphere, where it plays a crucial role in the water cycle by condensing to form clouds and precipitation.
How does air pressure increase?
According to experts, the increase in air pressure is based on the non-moving conditions (hydrostatic pressure) of mass in the air. When air mass becomes heavy, this increases air pressure levels.
Why are the upper parts of the atmosphere not part of the biosphere?
The upper parts of the atmosphere are not part of the biosphere because they lack the necessary conditions to support life. It is too thin to provide oxygen and protect against harmful radiation. The biosphere includes only the regions of Earth where living organisms can exist and thrive.
What is the most common gas to the least common gas?
Nitrogen is the most common - 78,o84 %; the lowest concentration is for ammonia - extremely low traces.
3 functions of earth's atmosphere?
1. It saves earth from harmful rays of sun
2. It controls the temprature and does not let earth cool faster in night of heat up during day.
3. It holds the important gases like oxygen, carbon di-oxise etc. which is helpul for us or plants.
Does cold air exert more pressure?
It depends on the situation. In a contained vessel (eg a tyre), then hot air would exert a higher pressure.
In general outside the pressure is (fairly) constant, and it is the density which changes with temperature. Imagine if this weren't true; you could have two pockets of air next to each other at different temperatures, and thus also at different pressures. In reality this leads to the pressure region expanding (and so decreasing in pressure), squashing the lower pressure region (increasing its pressure). This would continue until the pressures were the same in both regions.
What is the two highest layers of the atmosphere?
The thremosphere is the layer of the atmosphere that has two layers within it. The Thermosphere is the layer farthest from Earth's surface. The first layer of the thermosphere is the Ionosphere, and the second layer of the thermosphere is the exosphere
What is mar's atmosphere mostly composed of?
Mars' atmosphere is mostly composed of carbon dioxide (95.3%), with smaller amounts of nitrogen (2.7%) and argon (1.6%). There are also trace amounts of oxygen and water vapor in the atmosphere.
What are the Dominant Atmospheric Gases for Earth?
The dominant atmospheric gases for Earth are nitrogen (78%) and oxygen (21%). Together, these two gases make up about 99% of Earth's atmosphere. Other gases such as argon, carbon dioxide, and water vapor make up the remaining 1%.
What does the earth's atmosphere do?
The earth's atmosphere saves us humans from dieing from the suns deadly rays. It is like a shield that saves the knight from a knife. Or putting a blanket over the earth's atmosphere.
The Earth's atmosphere also creates rain. In the summer on a hot, sunny day, water evaporates, and when the steam hits the atmosphere, the steam condensates into water, making rain to fill our lakes, streams, etc.
What is the windiest place in England?
The windiest place in England is usually considered to be the Outer Hebrides, particularly the island of Tiree. Its exposed location means it often experiences strong winds coming in from the Atlantic Ocean.
Swamps are created in low-lying areas where water collects and saturates the soil. They form when water from rivers, rainfall, or groundwater accumulates in a region with poor drainage, leading to the growth of water-loving plants like mosses and cattails. Over time, these plants and organic matter build up, creating a wetland ecosystem known as a swamp.
How does the air plant survive without living in soil?
Air plants, also known as tillandsias, absorb moisture and nutrients through their leaves from the air. They have specialized trichomes (small hair-like structures) that help them to capture water and nutrients. This adaptation allows them to thrive in a soilless environment.
Which layer of the earths atmosphere protects the earth from these dangerous ulterviolet?
The ozone layer, found in the stratosphere, protects the Earth from dangerous ultraviolet (UV) radiation by absorbing and reflecting much of the UV light that comes from the sun. This helps to shield living organisms on Earth from the harmful effects of excessive UV exposure, such as skin cancer and damage to the environment.
What happens when particles and gas molecules in the atmosphere reflect and bend solar rays?
The process of scattering occurs when small particles and gas molecules diffuse part of the incoming solar radiation in random directions without any alteration to the wavelength of the electromagnetic energy. This factor also causes our sky to look blue because this color corresponds to those wavelengths that are best diffused. If scattering did not occur in our atmosphere the daylight sky would be black.
What types of long-term changes to the earth's climate might be associated with global warming?
# As the earth grows warmer, malaria-carrying mosquitoes will reach further north and south spreading the disease. # Warmer oceans will mean stronger hurricanes and tornadoes. Damage to countries and cities. # Thawing of the permafrost in the sub-arctic regions will release huge amounts of carbon dioxide and methane gas, which is a 20 times more dangerous greenhouse gas than carbon dioxide.
# Droughts and heat waves will be common and water will become in very short supply. There may be wars fought over water, as large rivers flow through several countries.
# The developed food supplies of countries will be wiped out, as the land becomes too dry for the crops. Cattle and sheep won't have pasture to survive. The price of food will go up and many people won't be able to live.
# Economic cost of treating diseases, rebuilding cities after hurricanes, providing water for drinking and sewage disposal will do a lot of damage to the world's economies. # Polar icecaps melting bring four problems: * Sea levels will rise from land-based ice melting (sea ice is already in the water so it won't raise the sea level if it melts). There are over five and a half million cubic miles of ice, glaciers and frozen snow. If this all melted at once, sea levels would rise by 230 feet, swamping many countries. Luckily nobody thinks this will happen all at once.
* All that ice is fresh water, so if it melts it will desalinate the oceans. This may change the patterns of the ocean currents that will seriously affect the climate. * Warmer temperatures in the polar regions will cause serious problems to animal life, which may not be able to adapt to the new conditions. * At present the ice caps form an enormous white surface which reflects a lot of heat back away from the land. If the ice goes, then the dark land below will absorb heat more easily, speeding up the global warming process.
Explain how anthropogenic changes in atmospheric composition are responsible for global warming?
The greenhouse effect has been keeping the Earth warm enough for human life since its beginnings. Infrared radiation comes from the sun into our atmosphere. The greenhouse gases of water vapor, carbon dioxide (CO2), methane and ozone (and a few others) prevent some of this heat reflecting back into space, thus keeping the planet warm.
However, since the 18th century, when we began to build factories, invent vehicles and produce electricity, humankind has been slowly putting more and more CO2 into the atmosphere. Every time we burn coal, gas or oil we increase the amount of greenhouse gases.
Forests too, which absorb carbon dioxide, have been cut down, and are still being cut down, all over the planet. With fewer trees, more of the CO2 goes into the atmosphere.
In 1800 the world population was less than one billion. Today it is close to 7 billion. Seven billion people wanting food, water and electricity and a share in the good life make a colossal demand on the resources of our planet.
So the increased greenhouse gases keep in more of the sun's heat. Global warming!
What does the atmosphere provide?
The atmosphere provides oxygen for living organisms to breathe, regulates the climate by trapping heat, protects Earth from harmful ultraviolet radiation from the sun, and enables weather patterns through processes like evaporation and condensation.
Does temperature decrease as wind speed increases?
No, temperature does not decrease as wind speed increases. Wind speed and temperature are independent of each other. Wind can affect how we perceive temperature through wind chill factor, where the faster the wind blows, the cooler it feels on our skin.
What is the most valuable resources in the atmosphere?
One of the most valuable resources in the atmosphere is oxygen as it is essential for the survival of most organisms. The ozone layer is also crucial as it protects life on Earth by absorbing harmful ultraviolet radiation from the sun. Additionally, water vapor plays a vital role in regulating the Earth's climate through the greenhouse effect.
