Answer: The impact craters are hard to identify because of the following reasons such as-

Continuous weathering and rapid erosion- The rocks on earth rapidly undergoes weathering and erosion, since millions of years ago, as a result of which the impact craters are affected, because it removes the features that could help us in determining that it is a crater. This erosion are caused by the agents such as wind, water and ice. The different parts of craters becomes hard to recognize.
Tectonic activities- The plates movement at the convergent, divergent and transform boundary has been continuously taking place and the plates are destroyed and new plates are created. Due to this, the previously existing craters are removed from the earth's crust. So it has become difficult to find the old craters.

Zina [86]

Answer:

Al inicio del siglo XX, varias eran las naciones que se disputaban entre si el liderazgo económico mundial.

En Europa, naciones como Gran Bretaña, Austria-Hungría, Francia y Alemania se encontraban entre las más ricas del mundo. Especialmente importante eran las posiciones de Gran Bretaña, sustentada en su gran extensión imperial y la explotación mercantilista de sus colonias; y Francia, impulsada por sus colonias y su consolidado estatus hegemonía. Por otra parte, Austria-Hungría era una nación plenamente industrializada, conformada por los sectores mas pudientes de Europa Central, y con ambiciones imperialistas en los Balcanes que le garantizaban el acceso al mar y a recursos naturales de la región. Por último, Alemania, que se había unificado tras la guerra Franco-Prusiana, también había incurrido en un rápido proceso de industrialización, que moldeó una economía productora de manufacturas y altamente militarizada.

Adicionalmente, en el continente americano, el surgimiento de los Estados Unidos como una potencia tras el proceso expansivo en el Pacifico y el Caribe lo depositó como una nación productora de bienes industriales y basada en el comercio interoceánico con naciones como Gran Bretaña y Francia.
