Explanation:
The rock cycle is powered by the internal and the external heat engines.
The sun is the ultimate source of energy that drives surface processes.
The heat from radioactive decay, frictional heat, accreted heat during the formation of the earth all combines to drive subsurface event.
- Surface events that impacts the rock cycle are weathering, erosion, transportation and deposition of sediments.
- Surface events leads basically to the production of sediments.
- The agents that drives the production of these materials are the wind, water and glacier.
- The sun is the major drive for the formation of these agents.
- The process leads to the formation of sedimentary rocks
For the subsurface process, the internal heat engine provides the energy that powers the convection current within the mantle.
This process leads to the formation of igneous and metamorphic rocks.
Where plates diverges and converges, igneous rocks form due to the upwelling of magma.
At convergent margin, a subduction zone allows for the changing of rock type into a metamorphic one. This is due to the temperature and pressure in those areas.

Answer:
d. may be a distinct entity or a building block of a more complex organism.
Explanation:
A cell is a structure that is able to live freely as it can perform all the vital processes that are required for life. Unicellular organisms have a single cell in their body. Therefore, the single cells may exist independently in the form of unicellular organisms such as Amoeba, Chlamydomonas. Similarly, many cells together form the multicellular bodies of complex organisms. These cells may be loosely packed as in sponges or may show tissue/ organ or organ system level of organization.
Answer:
The answer is B (determining costs of environmental preservation)
Explanation:
Forest engineers plan/direct programs for forest harvesting, reforestation, prevention and control for forest fires, environmental protection, and insect and disease outbreaks.
Using this information, we can clearly cross of A, C, and D. Leaving us with B, which completely lines up with our information on the job.
Epiphytic and Parasitic plants grow on plants.
