Answer:
Greece's steep mountains and surrounding seas forced Greeks to settle in isolated communities. Travel by land was hard, and sea voyages were hazardous. Most ancient Greeks farmed, but good land and water were scarce. ... Many ancient Greeks sailed across the sea to found colonies that helped spread Greek culture.
Explanation:
Answer:
Yes, Nomadic way of life reflects the adaptation of the tribal group.
Explanation:
Nomadic life refers to a lifestyle where the person doesn't have a fixed habitat. They keep moving from place to place in search of food and shelter. Due to scarcity of food and shelter at one place, people used to keep moving from one place to other. This shows how adaptive these people were. They used to easily adapt themselves to the place they used to travel.
Nomads travel in groups or tribes. They have their own distinct form of living style.

The ocean floor preserve evidence of past magnetic reversals because c) the ocean floor is uniformly old, preserving the earth's 4.6 billion history.
<h3 /><h3>What subjects need to be studied to study the earth's magnetism?</h3>
Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.
The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.

<span>Copper
is a chemical element with symbol Cu and atomic number 29. It is a
soft, malleable, and ductile metal with very high thermal and electrical
conductivity. A freshly exposed surface of pure copper has a
reddish-orange color. Copper is used as a conductor of heat and
electricity, as a building material, and as a constituent of various
metal alloys, such as sterling silver used in jewelry, cupronickel used
to make marine hardware and coins, and constantan used in strain gauges
and thermocouples for temperature measurement.</span>
