What gas has made up the largest portion of earths atmosphere for most of earths history?
Nitrogen has made up the largest portion of Earth's atmosphere for most of Earth's history. It currently makes up about 78% of the atmosphere.
What are the small pieces of rock that enter earths atmosphere at speeds of 15 to 70 k's and burn up called?
They are called meteoroids when they enter Earth's atmosphere. As they pass through the atmosphere, friction causes them to heat up and produce a bright streak of light, known as a meteor. If any part of the meteoroid survives and lands on Earth, it is then called a meteorite.
Would you find nitrogen in the earths atmosphere?
Yes, 80% of the Earths atmosphere is made up of nitrogen.
What causes seismic waves to change speeds as they move through earths layers?
Seismic waves change speeds as they move through Earth's layers due to differences in the physical properties of the materials in each layer. Factors such as density, rigidity, and composition of the rock can affect how fast seismic waves travel through them. The waves can speed up, slow down, or change direction as they encounter different materials with varying properties.
Most of the earths atmosphere is made up of what gas?
Nitrogen makes up about 78% of Earth's atmosphere.
When the north end of the earths rotation axis is pointing at the sun what happens?
The northern part of the Earth warms up. It is the Northern Summer.
Did the recent earthquake in japan speed up the earths rotation?
No.
What happens to your breathing when you hyperventilate?
It speeds up.
What happens to an object longer it falls?

What happens to the heart rate when one is startled?

What happens to the ECG when your heart speeds up?
An ECG stands for an electrocardiogram, a reading of the rhythm of your heart. What happens to the ECG when your heart speeds up is that the reading will change.
After defibrillator implant what happens if heart speeds up quickly?
it shocks it
What happens when water flows down a slope?
it speeds up
Does Airplanes Have to keep up with earths rotation when traveling over seas?
No. An airplane with weak, medium, or strong engines flies slow, medium, orfast through the air, and the air is keeping up with the Earth's rotation.
What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
What happens to the circulatory system when a man goes from standing to jogging?
It speeds up.
How are earthquake vibrations used to study earths layers?
These vibrations change speeds and directions when they go into different layers of the Earth.
