What are the issues and problems about lithosphere?

Answer 1

Mining

Rhetorical: What happens when it rains or precipitation occurs wherever there is a mine? How does this effect the natural water system?

Waste Management

Example: The lost plastic island in the middle of the Pacific Ocean, ranging the size larger than Texas and water 6 times thicker in plastic than that of plankton. These plastics come from around the world because of rivers and streams all leading to the ocean, the surrounding continents are solely responsible for this non-biodegradable waste floating island

Agriculture

Example: Pesticides, herbicides, river irrigation, etc. True as it may be that these things are helpful to to farmer, but what happens when the pesticides and herbicides spread outside the field because of wind or other weather patterns? How much is too much to take from the river to irrigate farms? What will be left?

Answer 2

1. pollution-caused by dumping of toxic chemicals on the soil such as: nuclear wastes, garbage, fertilizers and animal excretion which eventually result in the contamination of the soil

2. deforestation- cutting of trees may lead to the exposure of the soil to extreme heat causing it to infertile and the chance of erosion is increased.

Answer 3

The pole of rotation for the opening of the Red Sea at 36.5°N, 18.0°E (Arabia from Africa) implies the fastest spreading rates are in the south and are about 50% less in the north. Various studies show the spreading rate in the south to be about 1 cm/yr over the last 4-5 Ma. Problems arise as to the nature of the lithosphere beneath the northernmost Red Sea. The problem is further complicated by the fact that the Red Sea may have evolved in three phases. The first is the Gulf of Suez phase (mainly Oligocene), the second corresponds to the first (62 km) movement along the Aqaba-Dead Sea shear (?latest Oligocene-early Miocene) and the third to the second (45 km) movement along the Aqaba-Dead Sea shear (Plio-Pleistocene). These motions and their implications for the northernmost Red Sea are assessed.

The northern Red Sea differs from the central and southern Red Sea in having no clear magnetic lineations. Only a few isolated circular anomalies are observed. There are two possible explanations:1.

(1) there is extremely thinned continental lithosphere occasionally pierced by strongly magnetised volcanic centres, or,2.

(2) the oceanic lithosphere is present but without magnetic anomalies.

Answer 4

People taking from the lithosphere (the crust and upper mantle of the earth), and not understanding that once you take from the lithosphere, it doesn't come back-at least for a very long time. For example, oil took millions of years to form, and we use it every day. After a while, we won't have any more.

Answer 5

really odes not affect in any way it just a stpid question ask by teachers
