Answer:
crust lower mantle and upper mantle
Explanation:
Water and carbon dioxide are usually the most abundant gases emitted during basaltic volcanism.
Answer:
A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwater of a stream system would have a _____.
high gradient, and a narrow and shallow channel with no floodplain
Explanation:
A bedrock valley has no alluvium mantling the bedrock over which it flows. Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas. They may also be deposited at lakes or river banks. Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.
Answer:
Ophiolites
Explanation:
Ophiolites are regarded as a part of the Earth's oceanic crust and the underlying upper mantle which has moved up above the sea level thereby exposing it to the surface. They usually form a part of the continental crustal rocks.
Ophiolites are important and greatly influence Geologists having an idea about the composition of ocean crust.
Answer:
Norway
Explanation:
Officially there are three countries that compose Scandinavia, Norway, Sweden, and Denmark. Occasionally, Finland, Iceland, Faeroe Islands, and Aaland Islands are included, but that is only for local usage.
Out of the three countries, the one that has the biggest elevation is Norway, with Sweden coming as second, and Denmark having the lowest elevation. Norway's average elevation is 460 m. Sweden's average elevation is 320 m. Denmark's average elevation is only 34 m, making it the fifth joint lowest country in the world.
Norway has the highest elevation out of the three because the around half of the country is dominated by mountains, while Sweden also has mountains, it is mostly dominated by lowlands, and Denmark is entirely very low, lacking a single mountain or even a higher hill on its territory.
