Answer:
Para empezar, la Tierra no es una esfera perfecta. Y cuando gira sobre su eje (una línea imaginaria que atraviesa el mundo desde el Polo Norte al Polo Sur), su rotación se parece más a la de una peonza que a la de una esfera, bamboleándose y desviándose continuamente. Es lo que se conoce como "movimiento polar".
Las mediciones realizadas durante décadas demuestran que, solo durante el siglo XX, el eje de giro se desplazó alrededor de 10 cm por año. Lo que, durante todo el siglo, supone un desplazamiento de más de 10 metros. Ahora bien, ¿a qué se debe exactamente esta deriva?
Un equipo de investigadores de la NASA ha utilizado datos observacionales que abarcan todo el siglo XX y ha conseguido, por primera vez, identificar las causas del desplazamiento. Son tres: la pérdida de masa, principalmente en Groenlandia; el llamado "rebote glacial" y, por último, la convección del manto. El estudio se acaba de publicar en Earth and Planetary Science Letters, y cualquier persona que esté interesada puede acceder a una simulación interactiva de cómo los varios procesos contribuyen al "bamboleo" del eje de rotación terrestre.
'La explicación tradicional - afirma Surendra Adhikari, investigador del Jet Propulsion Laboratory de la NASA y autor principal del trabajo- es que un solo proceso, el rebote glacial, es responsable de este desplazamiento del eje de rotación terrestre. Pero recientemente, muchos investigadores han especulado que otros procesos podrían tener también grandes efectos sobre él. Elaboramos modelos para un conjunto de causas que se consideran importantes para impulsar el movimiento del eje de rotación. Al final no identificamos uno, sino tres conjuntos de procesos que son cruciales. Y la fusión de la criosfera global (especialmente Groenlandia) a lo largo del siglo 20 es uno de ellos".

Answer:
Brainliest pease
Explanation:
The primary goal of European expansion and colonization was to acquire land and resources to produce exports to sell for profit on the growing trans-Atlantic market. Profitable production demanded significant labor resources. The elite and entrepreneurial western Europeans who settled in the Americas sought laborers to cultivate cash crops, mine for precious metals, tend livestock, provide domestic service, and work in various artisanal trades. The labor sources they drew from to fill this demand included European indentured servants and convicts, free and enslaved indigenous people in the Americas, and enslaved Africans purchased through the developing trans-Atlantic slave trade. This meant that early colonial labor forces in the Americas were often a mix of Europeans, American Indians, and Africans. In large plantation areas, however, enslaved Africans and their African American offspring increasingly became the dominant laboring population. This section outlines how various historic factors led to African slavery taking a central role in supplying labor and skills to develop New World plantations and economies.

O A. Power is divided into many levels.
B. The people get to make laws for the country.
C. Decisions are made by a group of people rather than one person.
n
D. Laws are made for the entire country.
Answer:
I believe it is A, Power is divided into many levels.
Explanation:
Honestly, I just got out of civics so I would not trust me exactly but I think its A. A federal system is a split up government and a unitary system is just centralized at the national level. That would mean it would take longer to get things done with a split up government, right?
A federal system of government more complex than a unitary system as in the federal system of government, powers are divided into many levels. Hence, Option A is correct.
What is the system of government?Under this term, there are basically two types of systems of government. The first is federal , and the second is unitary. Under the federal system of government, powers are divided among the states as well as the central body of governments.
While in the case of the unitary system, powers are in the hands of the person who is in the ruling position and only in the center or only at the top position or the higher authority.
This is the basic reason that makes the federal system of government more complex in comparison to the unitary system of government.
Thus, Option A is correct.
