Drainage basin - the area of land drained by a river.
Catchment area - the area within the drainage basin.
Watershed - the edge of highland surrounding a drainage basin which marks the boundary between two drainage basins.
Source - the beginning or start of a river.
Confluence - the point at which two rivers or streams join.
Tributary - a stream or smaller river which joins a larger stream or river.
Mouth - the point where the river comes to the end, usually when entering a sea.
Hope this helped :)
Indentured servants. The headrights system allowed planters to be given 50 acres of land for every person they payed for to come over.
Answer:
Option (3)
Explanation:
Mid-oceanic ridges are the regions along which two distinct plates move away from one another. This type of plate boundary is known as the divergent plate boundary.
Whereas a rise occurs along a divergent plate boundary and is mostly associated with the region of hot-spots, where the magma is forced to rise up forming a gently steeper underwater highland area.
Both these features occur in a divergent plate boundary and plays an important role in pushing the continents apart. So we can conclude that the rises are mostly associated with the region of hot-spots, and ridges are formed due to the seafloor spreading at divergent plate boundaries.
Hence, the correct answer is option (3).
Answer:
B) Distinctly alkaline diagnostic horizons, thin profiles, lack of organic material, and dominance of sandy materials are features most closely associated with aridisols.
Explanation:
The aridisols are types of soils that are found predominantly in arid areas. They are soils that are not considered as fertile, and are near the bottom by quality of soils. These soils are lacking organic material, and also are very exposed to erosion, with the primary reason being the climate, as it doesn't allow for lot of vegetation to grow. The horizons of the aridisols are distinctly alkaline diagnostic ones, with the profiles being very thin and labile. The top layer of the soil is dominated by sandy material, which is a result of the extensive weathering and erosion in their surroundings, so the wind is mostly transporting small sandy grains and covers most of the area with them.
Answer:
<u>Fossil fuel- </u>The sources of fossil fuels are directly from the plants and animals, that are buried millions of years back and are converted into fossil now.
The consumption of fossil fuel leads to the emission of carbon into the atmosphere that is responsible for the increasing global temperature. This is one of the major problem of fossil fuel use.
<u>Nuclear fuel-</u> Nuclear fuels are derived from the radioactive elements such as uranium, strontium and potassium.
One of the major problem of using nuclear fuel is that it releases radioactive waste, that are harmful for various life forms.
<u>Renewable fuels-</u> This are renewable energy that can be generated again and again and are directly derived from the wind, water and the sun. For example, wind mill, solar panels and dams.
One problem of renewable fuels is that it has a lower production of energy such as electricity in comparison to the fossil fuels.
