According to one hypothesis, life on earth emerged from (bluegreen algae/ amino acids/ molten metals/ crustal rocks) in the presence of large amounts of gasses seeping from deep ocean vents. ANother process called primordial soup suggests that the formation of life was due to the effects of (lightning/sunlight/gravity/meteorites) in earths atmosphere.
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Explanation:
Answer:
C.) influence how land is used
Explanation:
Among the physiographic and archaeological variables used for the elaboration of the settlement pattern are the altitude, the phytogeography, the area covered by the sites, the types of sites, their distance from the water, the type of water sources, the number of low floor structures per site, the diameter and depth dimensions of the low floor structures, the chronology obtained from radiocarbon and thermoluminescence analysis, the insertion into the terrain model, the solar orientation, the prevailing winds and the field of eyesight. The compilation of these archaeological distribution and implantation data and the observation of their characteristics aim to create a settlement pattern of the populations of origin of a given area.
I think the two sources would be drip irrigation which is like a river, lake, groundwater, etc... The second source could be is making a new irragation system that could deliver water faster.
