About every 50,000 years, the Earth's magnetic poles flip. As basalt emerges from the ocean floor due to seafloor spreading, the iron within it aligns according to the magnetic pole's position. Paleomagnetism is the study of this magnetic orientation in ancient rocks. So, if you examine a section of seafloor and identify three areas that show magnetic pole reversals, you can determine that approximately 150,000 years have elapsed based on the frequency of those reversals.

gogolik [350]

Answer:

Mahusay na epekto sa heograpiya.

Paliwanag:

Mayroong isang malapit na kaugnayan sa pagitan ng klima at heograpiya sa Asya dahil ang klima ay nagreresulta sa mga magkakaibang uri ng lupain. Ang mga rehiyon malapit sa ekwador ay may mainit na klima at ang mga lupa rito ay kadalasang disyerto at may kaunting halaman, samantalang ang mga lugar malapit sa karagatan o malayo sa ekwador ay may mas mainam na klima at mas mayayabong na halaman dahil sa masaganang pag-ulan at angkop na kapaligiran.

A) Why does NASA publish a different Star Finder every month? (1 point)
Natalka [282]

Answer:

The positions of the stars and constellations shift each month.

Explanation:

It's important to note that the Earth is in constant motion as it orbits the sun; as a result, certain stars that were previously visible from some locations on Earth may no longer be seen later.

This is why NASA releases a new Star Finder each month to track the movements and changing placements of stars and constellations.

Question 3 1.5 pts The geographical boundaries defining South Florida are universally accepted as being limited to the north by
Jlenok [340]

The answer is False

Explanation

Florida is a U.S. state located in the southeastern region of the country. Furthermore, Florida is categorized into North Florida, Central Florida, and South Florida. While these regions lack precise boundaries, it is incorrect to assert that they are defined by Fort Lauderdale and Cape Romano, as South Florida extends into areas north of both locations, such as Coral Springs and West Palm Beach. Consequently, the correct answer is False.
