The ocean floor preserve evidence of past magnetic reversals because c) the ocean floor is uniformly old, preserving the earth's 4.6 billion history.
<h3 /><h3>What subjects need to be studied to study the earth's magnetism?</h3>
Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.
The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.

<u>Answer:</u>
Justin and Scott participated in activities like riding a tuk tuk, scuba diving, eating street food, etc. while in Thailand.
<u>Explanation:
</u>
- Justin and Scott quit their jobs and traveled to all the seven continents of the world and made a brilliant TV show out of their traveling adventures.
- While in Thailand, they hopped to a few different islands out of the 300 islands that Thailand is made of.
- Here, they rode a tuk tuk which makes the baseline of the Thai public transport.
- They tasted the famous street foods of Thailand and also enjoyed scuba diving.
The warming of the Earth due to buildup of carbon dioxide and other gases that help trap energy is termed the greenhouse effect.
Because the exchange of incoming and outgoing radiation that warms the earth because heat trapped is close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
Green house gases:
1) Carbon dioxide (CO2)
2) Methane (CH4)
3) Nitrous oxide (N2O)
4) Industrial gases:
a) Hydrofluorocarbons (HFCs)
b) Perfluorocarbons (PFCs)
c) Sulfur hexafluoride (SF6)
d) Nitrogen trifluoride (NF3)
The concentration of greenhouse gases is increasing in large part because of the combustion of fossil fuels. Key sources of chlorofluorocarbons are solvents, refrigerants, and propellants.

Positioned in northern Asia, Russia is in both the northern and eastern hemispheres. The country is dissected by the Arctic Circle, and also separated into two recognized landmasses by the Ural Mountains; its land west of those mountains is referred to as European Russia, and includes the capital city of Moscow.
