Jupiter, Saturn, Uranus and Neptune are referred to as the Jovian Planets, or planets that are essentially big balls of gas, each are surrounded by many moons and rings.
Unlike Terrestrial Planets like the Earth, these planets lack solid surfaces and they have relatively small, dense cores that are surrounded by layers of gas, which is made mostly of hydrogen and helium.
Jupiter and Saturn is different from Uranus and Neptune because the first pair is made almost entirely of hydrogen and helium and some hydrogen compounds, while the latter pair are made primarily of hydrogen compounds with smaller traces of hydrogen, helium, metal and rock.
As for the planets' interior, both Jupiter and Saturn have layers of metallic, liquid and gaseous hydrogen extending outward, topped with a layer of visible clouds.
On the other hand, Uranus and Neptune have cores of rock, metal, water, methane and ammonia. The layer surrounding the core is also made up of hydrogen that is covered with a layer of visible clouds.
The reason why the Midwestern United States have a very fertile soil, but Canada doesn't, despite both of them being covered by glaciers until relatively recently, and both having the same age of soil, is the climate and vegetation.
Canada is much colder than the Midwest, its winters are longer, and the summers mild, while the Midwest has higher temperatures, prolonged period of drought, and seasonal rainfall.
Because of this, Canada has been covered by coniferous forests. They leave relatively little biomass, and also the climate is making the decomposition of the biomass very slow, thus resulting in relatively poor soil quality.
In the Midwest, the climate is perfect for the development of the grasslands. The grasses grown and die each year. They live a lot of biomass, and the higher temperatures contribute that the biomass decomposes pretty quickly, thus resulting in good quality soil.
Answer:
d. It involves the use of expert judgment to develop forecasts.
Explanation:
Forecasting :
Forecasting is the prediction technique of future demand by using past data.
The type of forecasting:
1 .Qualitative
In this technique ,expert gives own opinion regarding the future demand of any service or product.
2. Quantitative
In this technique
1 . The information can be quantified
2.Assume that future demand will follow a past demand curve.
3.. It can be used when past information about the variable being
forecast is available.
In the quantitative forecasting pert judgment does not use to develop forecasts.
Option d is the correct answer.
d. It involves the use of expert judgment to develop forecasts.
I think it might be either wind power or hydro electric, but because new zeland has many rivers and reservoirs, i think it might be hydro electric power.
