If you look at the "memory" of the rocks being created and moving away from each other at the mid-Atlantic ridge, you can see where the magnetic poles flipped from north to south and back again.
<span>Looking at the rocks each side of the ridge shows that they are magnetic mirror images of each other and therefore that the surface of the Earth (at this point) is moving away from the ridge.</span>
Answer:
Is the object made of ice and dust? If so, it is likely a comet.
Explanation:
Comets are the bodies of the solar system that have the smallest diameter in relation to other bodies. Each comet has its divinity structure in the nucleus, hair and tail and its composition is composed of rock, dust and ice. This ice is quite dirty, because of all the dust and can make up most of the comet, reaching dozens of tons, but it can also be presented in smaller quantities.
Answer:
The galactic city model is also known as the peripheral model. The model is based on the city of Detroit, Michigan, and is made up of an inner-city, with large suburban residential and business areas surrounding it. These areas are tied together by transportation nodes, like beltways, to avoid traffic congestion.
Burgess, The City, 1925). The theory posits concentric zones round the central area, defined by their residential composition, moving from the very poor and socially deviant, in the inner zone of transition, to a peripheral suburban commuter ring.
The sector model, also known as the Hoyt model, is a model of urban land use proposed in 1939 by land economist Homer Hoyt. It is a modification of the concentric zone model of city development. The benefits of the application of this model include the fact it allows for an outward progression of growth.
