An archaeologist studies the lives of early humans by examining artifacts. Archaeology is essentially the study of human life, as well as material culture and environmental data which can explain how people in history lived. This includes prehistory and history. Archaeologists use different ways to identify this through surveying, excavation and analysis of data collection.

A. Describe the roles of mechanical and chemical weathering in the formation of the sediments that are eventually incorporated i

Serhud [2]

Answer:

As explained below.

Explanation:

Sedimentary rocks that are formed due to the accumulation of sediments that are derived from the deposition of small particles and their cementation of minerals and organic particles in the seafloor by the impact of various geological and earth processes like the wind, water, and glacier erosion.

Earth's crust is covered by 73% of sedimentary rocks and about 8% of the total crustal surface. Based on their formation, these rocks are thus classified as Siliciclastic, Carbonate, Evaporite, Iron-rich, and Phosphatic sedimentary rocks.

The color of these rocks is always determined by the iron and oxide contents, their size texture is a result of the density and permeability of the rocks like in the case of sandstone and limestone.

The relationship between the plate tectonics and the earthquakes is explained through the seismic waves that travel; through the three-layer of the earth from core to mantle to crust.

Earthquakes are directly related to plate boundaries as these are areas where these waves come out in the form of shocks and shaking of lands thus we expect of seeing three types of boundaries as Convergent, Divergent and Transform.

Why are felsic lava flows so much more viscous than mafic ones?

ira [324]

Answer:

Magma are the hot molten materials that rises up towards the surface due to the increasing force from the depth. These magma when comes out to the surface then they are considered as lava.

The felsic lava are those in which the amount of silica and aluminium is very high. Due to this high silica content, the viscosity is high. The amount of silica present in magma or lava is directly proportional to the viscosity of magma or lava. The felsic lava due to its high viscosity flows sluggishly.

Whereas, the basic lava are those in which the silica content is significantly less. Iron (Fe) and Magnesium (Mg) is mostly present in this type of lava. As a result of which it flows easily without any difficulty.

This is the reason why felsic magma (lava) are more viscous compared to the mafic magma (lava).
