Answer:
Option (1)
False
Explanation:
The mid-oceanic ridge is one of the main features in the divergent plate boundary. Seafloor spreading takes place along this ridge, where the lithosphere becomes thin because of the uprising magma. The magma erupts at the surface forming a ridge which is commonly known as the mid-oceanic ridge.
As the magma melts at this ridge due to the decompression process, it solidifies and forms young basaltic igneous rocks. These are geologically the youngest rocks. With the increasing distance right from the mid-oceanic ridge, the age of the rocks increases.
Thus, the correct answer is option (1).
At this mid-oceanic ridge, when the magma erupts at the seafloor, it is comprised of magnetic minerals, which shows a specific pattern in the orientation of the earth's magnetic polarity. This forms alternate stripes, that starts from the mid-oceanic ridge and eventually expand outward. This pattern of earth's magnetic polarity is found in all the mid-oceanic ridges on earth.
Hence the given statement is false.
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.
The equator is the warmest place on earth. It gets the most sun and is the closest to getting all of the heat. I know there is a scientific name but I cant quite recall it.
Answer:
b. grains traveling short distances (approximately 1 m) in the air
Explanation:
Wind is a very efficient erosion agent, and its action, particularly in areas of arid, semi-arid and desert climates, is responsible for transporting and depositing large volumes of sediments with the development of a typical wind landscape.
The diameter of the sand grains transported by the wind averages between 0.15 and 0.30 mm, with some fine grains up to 0.006 mm, all particles smaller than 0.006 mm are classified as dust. A grain the size of the dust is carried high in the air and a grain the size of the sand is carried forward near the ground by jumping (see figure 1). As the particle size increases, the attraction of gravity and air resistance also increase.
The soil surface particles are transported by the wind in three ways:
- By drag: the thickest particles (500 - 2000 microns).
- By saltation: medium particles (100-500 microns).
- In suspension: the smallest and lightest particles (<100 microns, 0.2 mm).
The <u>saltation</u> moves the particles by small jumps, in the direction of origin of the wind and normally does not remove them more than 1 centimeter above the ground. An individual grain rolls forward driven by the wind, until it bounces with a second grain. Once in the air, it is carried forward by the wind and drawn to the ground by gravity. It follows a parabolic path falling on the ground with an angle between 10º and 16º, and usually traveling short distances.
Yes it can, it can erode things such as mountains or slopes. Have a nice day!
