Answer:
Geothermal energy
Explanation:
The Yellowstone National Park is a wonderful park located in the United State, covering an area of about 3,500 square miles. This park is comprised of beautiful geological as well as hydrothermal wonders.
The old geyser found in this park is powered by the geothermal energy. This energy can be simply defined as the energy that is stored in the interior of the earth. This energy increases with the increasing depth and is basically used in the production of electricity.
Answer:
Option: C. Columbia
Explanation:
The Columbia River provides more than one-third of all the hydroelectric power in the United States. Hydroelectric power plants located on the river with generating capacity and contributed approx 44% of the total hydroelectric power in the nation. The steep slopes of the Columbia River and its streams make it ideal for the production of hydroelectric power.
Answer: The presence of seeds that need light to germinate in the farm.
Explanation:
There are some specie of seeds that germinate best when they are exposed to light.
If these seeds are covered in soil, it is very likely they they will remain dormant and not sprout until conditions improve.
These seeds only needs to be pressed onto the surface of the soil where they can easily access sunlight and kept moist to germinate.
Once the light from the Sun hits this seed they obtain the required energy needed for them to germinate.
Therefore when the farmer ploughed the field he was unknown to him, exposing the seeds to the much needed light.
The biggest Shia Muslim country is Iran (but it's not on the list). There is also a large minority in Iraq, Azerbaijan and Bahrain. Saudi Arabia has some small communities, but Yemen is divided almost in Half among the Shia and the Muslims - so the best answer is B! (but Kuwait also has a sizeable community and Quatar has about 5% of Shia Muslims)
1. The zone of aeration and zone of saturation are two separate zones in the soil. The zone of aeration is the top zone of the soil. In this zone the rocks and soil have pores that are only partially filled with water. The saturation zone lies below the aeration zone. This zone is composed of rocks and soil that have pores that are saturated with water.
2. The water manages to move much more easily through rocks and sediment that have larger pores. The reason for this is that the larger the pores, the more free space there is, so the water manages to flow through them without any particular problem. The rocks and sediment that have smaller pores are not allowing for the free flow of the water. The smaller the pores are the smaller the space for the water to pass through, so the water usually starts to accumulate and cause saturation.
3. The caves and the caverns have two basic differences, though it has to be mentioned that the caverns are actually a type of cave. The caves are natural openings that occur on the sides of the hills, mountains, and gorges, while the caverns only form in soluble rocks and have speleothems in them. A typical cave has only one opening, while the caverns have multiple openings, ranging anywhere from two to several tens of them.
4. The two major factors that determine how easily the water can move through rock or sediment are the size of the pores and are the pores connected or not. If the pores are larger and they are connected the water will be able to move easily through the rock and sediment. On the other hand, if the pores are connected or they are very small, the water will find it hard to move through them and saturate them.
5. The karst topography is a very interesting one. It has lot of caves, cavers, karst fields, springs etc. This topography forms because of the reaction between the bedrock and the water and carbon dioxide. The water and the carbon dioxide manage to dissolve because of the increased levels of acidity, so the rocks start to change their composition, and over longer periods of time, lot of different features start to form, creating the interesting karst topography.
