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.

Which lifting mechanism is most likely responsible for the abundance of rain in the Amazon Rainforest?
valina [46]

Answer: Convective

Explanation:

Convective Lifting is arguably the most common form of lifting and involves the heating of the Earth's surface such that surface water gets evapotranspirated from the ground and plants.

As the clouds rise, they encounter cooler temperatures and thus cool down and condense into clouds. Higher temperatures mean higher convection.

The Amazon lies on the Equator which receives the most direct sunlight so the surface gets heated a lot. Water therefore collects faster and condenses more over the Amazon which leads to more precipitation over the Rainforest.

What are the two important processes involved in lithification of sedimentary rocks?
goldenfox [79]

Answer:

B. Cementation and compaction

Explanation:

Sediments compact under pressure, then they lose fluids, these fluids cement together and eventually becomes solid rock, this process is known as lithification.

Cementation is when fluids from the loose rocks bind themselves together. If the loosely bound rocks are inorganic, they form and turn to clastic rocks but if it contains organic matter, it is known as bioclastic.

In essence, this destructive phase of sedimentary rock formation is known as cementation and compaction.
