Answer:
Explanation:
geography the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries.
Geography's two main branches are physical geography and human geography.
careers in geography- 1.Cartographer.
2.Commercial/residential surveyor.
3.Environmental consultant.
4.Geographical information systems officer.
5.Planning and development surveyor.
6.Secondary school teacher.
7.Town planner.
Answer:
1. Complex fault interaction, 2. Atlantic ocean, 3. divergent plate boundaries and mid oceanic ridges, 4. Rate of movment is 1 cm per year due to rapid spreading of lavas. 5. Upwelling of magma, 6. faults, folds and volcanism.
Explanation:
- The location of South America influences the development of earthquakes. Having s narrow continental shelf the plates of pacific and south America collide with each other.
- The mid oceanic ridge marks the new oceanic crust that is continuously being created as plate expand and the lithosphere becomes cooler.
- The presence of the divergent plate boundaries leads to their creation. The rate of movment of the plate is about 1 cm per year.
What are the solutions to log Subscript 6
Baseline (× squared + 8) =1 + log Subscript 6
Baseline (X)
× = negative 2 and x = negative 4
X= negative 1 and x = 8
x = 1 and x = negative 8
x = 2 and x = 4
The answer is b. Air pollution
Explanation:
Question 1:
B. Increased heat and pressure may change the sedimentary rock into metamorphic rock.
In a subduction zone, sediments are usually subject high temperatures and pressures by which they change into metamorphic rocks. Metamorphic rocks are described as changed rocks.
- In a convergent zone when a plate subducts beneath another, the rock is forced into an environment where heat and pressure is elevated.
- With available water, a metamorphic change occurs leading to metamorphic rocks.
- Along a subducting rock, different facies of metamorphic transformations are observed.
- This slowly goes from low grade to high grade metamorphic transformation.

Question 2:
A. Weathering and erosion.
Weathering and erosion are external processes that must have carved the canyon area from the surroundings.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- In the process of erosion, the rocks, sediments and soils are then carried away from their original position into other places.
- These processes combines and interacts to form powerful forces that causes denudation.
- The major agents here are wind, water, ice, glacier and gravity.

Question 3:
C. Igneous rock becomes sedimentary rock.
This change is rock cycle change from igneous to sedimentary rocks. This entails the remains of pre-existing forming clasts of sedimentary rocks.
- The granite that is disintegrated by the process of weathering is an igneous rock. These are rocks that forms through the cooling and solidification of molten magma.
- The sandstone that results from this process is a sedimentary rock. Sedimentary rocks are usually derived from pre-existing rocks.
- The process of lithification and sediment compaction under significant pressure causes the sediments to transform igneous rocks.

Question 4:
D. Clastic sedimentary rock forms from sediment, not from the remains of organisms.
The problem with the classification is that clastic sedimentary rocks are formed from sediments and not remains of organisms. Clastic sedimentary rocks are derived from pre-existing rock materials.
- Examples are sandstone, silt, gravel e.t.c
- They formed from sediments that gathers from the weathering of pre-existing rocks.
- The limestone that formed from the shells of organisms is a biochemical sedimentary rock and not a clastic.

Question 5:
C. The grains of the rock are aligned in a layered patterns.
The best feature that shows that a metamorphic rock is foliated is the layered arrangement of mineral grains in the rock. Due to intense nature of pressure and temperature metamorphic rocks are subjected to, most their minerals are usually aligned.
- Pressure can caused the long axis of some platy minerals to form a special texture giving them a schistose foliation.
- Temperature and pressure can combine to form a sort of metamorphic foliation known as gneissic layering in which the mica domains and quartz rich domains alternate simultaneously.
- In low grade metamorphism, we can a have sort of slaty cleavage developing too.
