Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
Answer:
No, economic opportunities can never outweigh the environmental damage because these two are interlinked with each other and degradation of one impact the other one in the same way
Explanation:
No, economic opportunities can never outweigh the environmental damage because these two are interlinked with each other and degradation of one impact the other one in the same way. Hence, if the environment is degraded for carrying out commercial activities, the economy will fall as there will be high pollution, increased consumption of non-renewable resources, global warming etc. that will require cost input for rectification thereby adversely affecting the economy.
Answer:
A. During warmer climates, glaciers melt and sea level rises.
B. During times of cooler climates, the amount of evaporation from the oceans decreases, causing sea level to rise
D. The amount of glacial ice stored on land affects global sea level.
Explanation:
- The global sea levels and the amount of climatic pattern are related as wit the rise of the global mean temp of over 1 or 2 °C the climate of the earth will ward and there will be a natural rise of the sea levels due to the stored ice gets melted and additionally the thermal expansion will also cause the expansion of the water levels in the sea and the oceans.
- <u>When the sea levels fall there is a shift in the hydrological cycle. Water is evaporated and is stored on the glaciers as ice. As proved by the interglacial periods when the sea levels were high er more than the normal about 20 meters.</u>
The unsaturated zone is the area of the subsurface that is above the groundwater table. The pores of the soil and rock in this zone contain both air and water.
<h3>What is the water table?</h3>
The water table is the subsurface border between the unsaturated and saturated zones.
The water table is an underground border that separates the soil surface from the area where groundwater saturates crevices between sediments and rock fissures.
At this point, the pressures of water and air are equal.
The unsaturated zone is the soil surface above the water table, where both oxygen and water fill the crevices between particles.
Therefore Option C is correct as it is where a person will immediately reach after drilling a well through an unsaturated zone.

It becomes brighter because, THE CORE CONTRACTS, RAISING THE TEMPERATURE AND EXTENDING THE HYDROGEN BURNING SHELL OUTWARD. This stage is called the hydrogen shell burning phase and during this phase the star grows luminous.
