One of the main reasons why some areas to the east of the pacific mountain ranges are having a desert climate is that the "<span>air loses much of its moisture as it moves from the pacific ocean eastward up the mountains." In addition, the significant influence of the Pacific Ocean proved to be a factor for desertification among these lands as it moderates temperature extremes.</span>
<u>Answer</u>: e) Volcanic activity in the region leaves behind valuable minerals.
<u />
<u>Explanation</u>: Volcanic activity has played an important role in the creation of the Cascade Mountains as they were originally created through the subduction of two continental plates.
It is well known that gold deposists are often found through volcanic systems. Water heated by volcanoes will become very acid and thus dissolve surrounding rocks. This water that will contain gold and other metals will then follow fractures through the bedrock towards the surface. In time, these will turn into gold veins or lodes.
Answer:
Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.
Explanation:
Answer:
high preasure
Explanation:
because there is very high pressure inside the earth
Answer:
biosphere
atmosphere
lithosphere
hydrosphere
Explanation:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
