Answer:
Geografía de la tierra.
Explicación:
La característica geográfica es responsable de la variación de las actividades climáticas, biológicas y humanas en América porque la geografía proporciona diferentes recursos que determinaron las actividades humanas en esa zona. La geografía cercana al océano tiene un clima moderado y la gente está relacionada con la pesca y el trabajo en los puertos comerciales, mientras que por otro lado, las regiones cercanas a la cuenca son planas donde la gente se dedica a la agricultura y otras profesiones afines.
<u>Answer:</u> The correct answer is Option b.
<u>Explanation:</u>
Nuclear fusion reaction is defined as the reaction in which lighter nuclei combine together to form a single heavier nuclei.
Another name for helium nuclei is alpha particle.
For the given options:
- <u>Option a:</u> The CNO cycle
This cycle is named as carbon-nitrogen-oxygen cycle. In this cycle, carbon absorbs a proton to form nitrogen which further absorbs a photon to form oxygen. Thus, helium particles are not getting fused in this process.
- <u>Option b:</u> The triple alpha process
This process is a set of nuclear reaction in which 3 alpha or helium nuclei combine together to form carbon nucleus.
The equation representing the fusion process follows:
- <u>Option c:</u> Photo dissociation
This is defined as the process in which a chemical compound is broken down by photons. Thus, helium particles are not getting fused in this process.
- <u>Option d:</u> The proton-proton chain
This process is a set of nuclear fusion reactions by which stars convert hydrogen nucleus to helium nucleus. The chemical reactions for this process are:
Here, fusion of protons takes place.
Hence, the correct answer is Option b.
Answer:
It divided Antarctica between the different countries that were trying to reclaim the country. It also permitted the scientific exploration of all the land
Throughout the quaternary repeated advances and retreats of polar ice caps ended in transferring of wilderness belt in the direction of the Equator that ended in extrade in the course and depth of dune-forming winds.
<h3>What is the Rub Al Khali made up of?</h3>
Rub Al Khal terrain is protected with sand dunes with heights as much as 250 meters (820 ft), interspersed with gravel and gypsum plains. The sand is of a reddish-orange color because of the presence of feldspar.
The terrain is characterized by brackish salt residences in a few areas, consisting of the Umm al Samim region at the wilderness's jap edge.
hence, Throughout the quaternary repeated advances and retreats of polar ice caps ended in transferring of wilderness belt in the direction of the Equator that ended in extrade in the course and depth of dune-forming winds.
