Is iron a part of the atmosphere?
Yes it is, but in small quantities.
What is cloud seeding and is it effective?
Cloud seeding - is dropping quantities of microscopic particles into the upper atmosphere - with the intention that water molecules will 'stick' to the particles - and thus create rain.
What is solar quantities?
Scalar quantities are physical quantities that can be described with a single value. They are unlike vector quantities which require both magnitude and direction.
Which planet's atmosphere has only 21 percent oxygen?
The oxygen in Earth's atmosphere comes from photosynthesis, which is carried out by plants and algae. Earth is the only planet known to have life, which is the only way we know of that would cause a planet to have an oxygen-rich atmosphere. Oxygen can form from the chemical breakdown of water via sunlight, but only in trace amounts.
Is there any oxygen on moon?
The Moon has an extremely thin atmosphere. It's about what you could get with a good roughing pump (forepump, rotary pump) in an Earth laboratory. However, it's not much like Earth's atmosphere at all, and in fact contains significant quantities of things like sodium (again, remembering that we're still talking about a pretty good vacuum here).So, for practical purposes: no, there is no air on the Moon.That's right, there's no air on the moon.
which quantities define momentum?
The quantities of production in mass of a particle with velocity describe momentum.
Is iron a part of the atmosphere?
Yes it is, but in small quantities.
What the axes of the production possibility frontier measure?
quantities of productive inputs
Are there any atmospheric gases on Mercury?
Yes, but in very small quantities. Very very small quantities, Mercury's atmosphere is basically a vacuum.
What gas can protect atmosphere?
Ozone, although in large quantities it can also be poisonous.
Which gas is present in very large quantities in the atmosphere?
The most abundant is nitrogen.
Why do scientists think that the first organisms did not need oxygen to survive?
Breathable oxygen, or O2, did not exist in large quantities in the atmosphere until after the evolution of photosynthetic organisms. Hence, early organisms had to have an anaerobic metabolism, or one that did not require oxygen. However, compounds containing oxygen, such as water, have always been necessary to organisms.
An athlete produces large quantities of sweat as a result the kidneys change the rate of urine production?
An athlete produces large quantities of sweat as a result the kidneys change the rate of urine production. This is because decreased urine production increases the amino acids in the blood.
What is the making of large quantities of goods that are exactly alike?
Such a term is commonly known as mass production.
What oxidized metal caused substantial quantities of oxygen to accumulate in Earth's atmosphere?
iron
A volcanic eruption can affect the atmosphere by?
adding large quantities of several gases, such as sulfur dioxide, to the atmosphere as well as volcanic ash and dust.
What is needed for a Milestone C decision review?
Capability Production Document (CPD)
