Answer:
A group or a chain of islands is called archipelago.
Explanation:
The seas and oceans are not just open spaces of water with nothing interrupting them, instead they have hundreds of thousands or even millions of islands rising from them. The islands vary in size, and what can be considered as an island is still debatable, but they can be anywhere from few tens of meters to hunderds of thousands of square km.
The chains or groups of islands are called archipelago. In order to distinguish them from one another they have to have some similraties and most often they need to have the same geological history and processes that created them. An archipelago can be formed in multiple ways. Along the subduction zones there are always archipelagoes, and this is due to the volcanic activity. Another creator of archipelagoes are the hot spots because they are static but the plates move on top of them, thus draging the islands from the hot spot and new rising above it. Also, if the characteristics of the topography of an area are such that when the sea levels rise, there can be a formation of an archipelago where the lower areas will be under water while the higher places would remain above water.
The correct answer is : Planetary accretion
In Planetary accretion theory, the universe was formed by accretion process, which is the accumulation of particles into a massive object by attracting more matter, forming all kind of astronomical objects such as stars and planets
Answer:
it is said that the Ice Ages began 2.4 million years ago and ended approximately 11,500 years ago.
Explanation:
During this time Carbon-Dioxide (a poisonous and warming gas) levels rose dramatically by about 180 ppm to 280 ppm.
This caused the major retreat of glaciers that ran across continents...
There were other gases but they were in VERY small amounts...

Warm, humid, growing, part of United States with important oil discoveries - <u>South</u>.
Northern part of this peninsula is heavily populated, near San Diego - <u>Baja California</u><u>.</u>
Vast forests and active volcanoes in the United States - <u>Pacific Northwest</u>.
Includes area around the American and Canadian shores of the Great Lakes - <u>Midwest</u>.
<h3>What is a sub-region?</h3>
This refers to the conceptual unit which derives from a larger region or continent and is usually based on location.
For instance, in the United States, the subregion of the country includes the Pacific Northwest, Midwest, Baja California, South etc.
Therefore, in this question, the sub-region were used to locate the region where we have:
- Warm, humid, growing, part of United States with important oil discoveries
- Northern part of this peninsula is heavily populated, near San Diego
- Vast forests and active volcanoes, in the United States
- Includes area around the, American and Canadian shores of the Great Lakes.
