Answer:
A) The outer planets consist mostly of gases .
Explanation:
Inner planet constitutes of the planets closest to the sun , i.e. , Mars , Earth , Venus , Mercury .
Outer planet constitutes of the planets farthest from the sun , i.e. , Neptune , Uranus , Saturn , Jupiter .
The inner planets of the Solar system are composed of metals and rocks and hence are of solid state and heavy .
Whereas , the outer planets are composed of mainly gases like hydrogen and helium and hence are light in weight .
Groundwater is important for us as it is the greatest source for freshwater, crop irrigation and agricultural activities.
In general, groundwater is present in reservoirs and aquifers below the surface of the earth and also most crucial natural source of water for any nation. Groundwater provides fresh drinking water to almost 50% of global population. With an ever increase in global population, the use of groundwater is also increasing.
The primary way of wasting fresh water is its overuse in households such as in kitchen, toilets for taking long showers, washing and bathing purposes.
We can save groundwater by avoiding unnecessary leakage, unnecessary showers, and decreasing shower time.

Answer:
The western and central European section of the plain covers all of western and northern France, Belgium, The Netherlands, southern Scandinavia, northern Germany, and nearly all of Poland; from northern France and Belgium eastward it commonly is called the North European Plain.
Explanation:
The North European Plain is a European region that covers Denmark, Poland, Germany, Belgium, Holland, and small parts of northern France and the Czech Republic. Some research accounts also include the southern United Kingdom, east Russia, Baltic States like Estonia, Latvia, Lithuania, and Belarus as part of this expansive plain. The North European plain also has lowly elevated plains tucked between the Central European Highlands on the south and on the coastlines of the Baltic Sea and North Sea to the north. The Baltic and the North Sea are divided by the North Jutland Peninsula which is also the nation of Denmark. The Great European Plain is formed where the North European Plain connects to the East European Plain. The Northern European Plain also occupies the territory under the Baltic Sea. Due to the plain's unique surface features, its geological structures are keenly studied by researchers.
Features
As part of the Great European Plain, the North European Plain lies below 500 feet in altitude, and has a relatively flat terrain. As a result, drainage is poor and frosty deposits cover much of the region and plain. The North European Plain also has several rivers like the Rhine, Oder, Weser, Elbe and Vistula. Along the Rhine River in the Netherlands, there is a well developed transport system, and a vibrant agricultural area making the area around it be densely populated. The plain is amongst the most fertile lands that are utilized for commercial farming in the world. There are also tiny farms strewn in the countryside of the North European Plains. The temperate climate and the average amount of rainfall in the North European Plain allows for growth of seasonal crops like maize, wheat, and rye. This makes the plain in the North European wheat belt region. Due to the plain’s fertility and flat terrain, it is among the most densely populated territories in Europe. The rivers that crisscross the North European Plain also draw in a large human population due to guaranteed water supply.
