Igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.
Let's look into the statements one by one:
Igneous rocks are formed only from material ejected during a volcanic eruption.
-This is not true because igneous rock can also be formed by the cooling down of magma inside a volcano or magma that was trapped in the crack of crust.
Igneous rocks are formed by the cooling and crystallization of molten rock.
-This is correct.
Igneous rocks are produced by the weathering and transport of pre-existing rocks.
-This is incorrect as igneous rock is formed by volcanism. The rock that are formed with the statement is sedimentary rock.
Igneous rocks are formed by the cooling of magma above earth's surface and lava below the surface.
-This is correct. Both intrusive and extrusive volcanic activity forms igneous rock after cooling down.
Igneous rocks are formed by recrystallization
-This is not true as recrystallization does not take place in the formation of the igneous rock. The rock formed by recrytillization is metamorphic rock.
Therefore,the igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.

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.
Answer:
Poor planning, and disease
Explanation:
The obstacles that the French faced while attempting to build a canal across Panama were diseases and poor planning. The French dealt with constant outbreaks of malaria and yellow fever, which slowed construction and caused the deaths of thousands of workers. The French also did not take into consideration the geographical differences between the Suez Canal region and the Panama region. The French had succeeded in building a canal at sea level in Egypt, and they mistakenly thought a similar design would work in Panama. However, the difference in the Atlantic and Pacific Ocean sea levels, as well as the difference in elevation of the Panamanian terrain, prevented them from building a sea-level canal. The United States knew about these two problems when they undertook the project. They took preventative measures by reducing the disease-spreading mosquito population and using a canal-lock system to overcome the elevation obstacle in Panama.
Answer: Anaerobic respiration or Fermentation
Explanation:
When we are engaged in intense physical activity such as running or riding a bike, the muscles need energy to function and they get this from aerobic respiration.
They will quickly run out of the oxygen required to sufficiently use aerobic respiration however and will turn to anaerobic respiration which can produce energy in the absence of oxygen.
As the body uses anaerobic respiration however, lactic acid is produced and builds up in the muscles. It is this lactic acid that leads to the muscles feeling sore.
