The direction iron in ocean rocks points
The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.
Explanation:
These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.
The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

ALS is a rapidly progressive and fatal neuromuscular disease. MS is a scarring and hardening of the sheath around the nerves in the brain, spinal cord, and optic nerve. MD is a muscular disorder with specific kinds of MD involving different muscles in the body. MD is almost exclusively hereditary
<h3>What is Amyotrophic lateral sclerosis (als) ?</h3>
The motor neurons steadily degrade and eventually die as a result of ALS. The brain, spinal cord, and all the muscles in the body are connected by motor neurons. When motor neurons are destroyed, they stop communicating with the muscles, which prevents the muscles from working.
- Five to ten percent of all ALS cases are familial, meaning the patient gets the illness from a parent. Typically, only one parent needs to have the disease-causing gene to have familial ALS.

You can't really expect to find water stored as a gas, as it cools to a liquid at room temperature. You could easily find evaporated water on a stovetop by boiling water, though.
Answer:
Atypical pneumonia
Explanation:
This is the type of pneumonia caused by uncommon microorganisms types and it’s usually very rare. This type of pneumonia has milder symptoms and can be caused by bacteria, fungi, Protozoa and virus.
It is also known as Walking pneumonia. It is very difficult to culture and can’t be easily detected.
