Answer:
Layer B is older than intrusion A
Intrusion A is older than layers C, D, and E.
Layer B is older than layers C, D, and E.
Explanation:
The laws of biostratigraphy can be applied to this lithological section in order to ascertain the relative ages of the beds.
Some of these laws that are applicable to this problem are:
- Principle of superposition of strata : the oldest layer is always at the bottom of sequence while the youngest is on top in an undisturbed rock sequence.
- Law of cross-cutting: when faults and fractures cuts through a rock sequence, they are younger than the rock they cross through.
- Law of intrusions: Intrusions are younger than the rock layers they cut through
The geologic history of the beds here can be interpreted as thus:
- Lithology B was first deposited
- Then an intrusion A occurred and terminated at B
- Layers C, D and E were then deposited.
The oldest layer here is B followed by the intrusion A and successful deposition of C, D and E in that order.
The correct answer is - c. east.
The Appalachian Mountains are located in the eastern part of the United States, and since the Rocky Mountains are in the western part of the country, it puts them east of the Rocky Mountains.
The Appalachians are a very old mountain range, they are dated to about 480 million years ago when they formed during the Ordovician Period. At their peak, these mountains reached heights similar to the Rocky Mountains and the Alps in Europe, but because of the natural erosion they have shrunk and nowadays are much smaller in height.
Answer:
The Yellow Sea
The west coast of the peninsula is bordered by the Korea Bay to the north and the Yellow Sea and Korea Strait to the south; the east coast is bordered by the Sea of Japan.

<span>The marine west coast climate is a biome characteristic of being located midway between the tropics and arctic or Antarctic regions of the world, most often between 35 and 60 degrees north. This climate's major characteristics are mild summers and winters and abundant annual precipitation. This ecosystem is highly influenced by its proximity to the coast and to mountains. It is sometimes known as the humid west coast climate or the oceanic climate. In additional to coastal plains and mountains, this type of climate is often characterized by glacial valleys and fjords.
Marine west coast climates are typically found to the west of large mountain ranges that cause fronts to collide and release all of their precipitation. Wet warm air from the coast rises and cools as it goes over the mountain. This causes the water in the air to cool and condense, resulting in rain, drizzle, and fog. Then drier air proceeds inland. This is known as the rain shadow effect, which in basic terms is when a mountain blocks the advance of wet weather, creating a dry biome on the other side and a wet biome on the ocean side. This results in a very special climate.
Think of areas such as British Columbia in Canada, Washington and Oregon in the United States, and most of the continent of Europe. Parts of Africa and Australia are also considered marine west coast despite not being located on a west coast of the continent.</span>
Answer:
gamma diversity
Explanation:
Gamma diversity
The name was given by R. H. Whittaker ,
<u>Gamma diversity </u>= the total species diversity in the landscape .
<u>Beta diversity</u> = the differentiation among the habitats .
<u>Alpha diversity </u>= the mean species diversity in sites , or at local scale .
The product of alpha diversity and beta diversity together gives the gamma diversity .
