Answer:
1. There is enough DNA in the average person’s body to stretch from the sun to Pluto and back — 17 times.
2. The average human body carries ten times more bacterial cells than human cells.
3. It takes a photon up to 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth.
4. At over 2,000 kilometers long, The Great Barrier Reef is the largest living structure on Earth.
5. There are 8 times as many atoms in a teaspoonful of water as there are teaspoonfuls of water in the Atlantic ocean.

Answer:
Drought is a condition, not a hypothesis. Drought is the lack of rain, or evaporation in excess of precipitation.
The CAUSE of drought is a multi-pronged hypothesis. It can be due to cyclic changes in ocean temperature (El Niño/La Niña). It can be due to rain shadow downwind of a mountain range. It can be due to fluctuations in the sun’s brightness. It can be the result of urban sprawl and resulting shifts in upwind evaporation/transpiration. It can be the result of climate bands shifting in response to changing atmospheric composition. It can be the result of agricultural practices upwind. It can be just bad luck, with a location consistently not being the whatever-percent chance of where it’s raining.
A) fresh water: fresh water means it is water that is fresh and it doesn't come from the sea or isn't polluted.
B) groundwater: it is presented beneath Earth's surface in soil pore spaces and in the fractures of rock formations
C) aquifer: it is a underground layer of water-bearing permeable rock.
D)irrigate: it is supply water to help land or crop grow.
E) physical water scarcity: it occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively.
F) economic water scarcity: it is caused by a lack of investment in water or infrastructure of insufficient human capacity to satisfy the demand of water in areas.
Hope this helped :)
Have a great day
They erode the earth, carrying along minerals and soils. When they melt, they deposit these materials, creating other landforms.
Answer:
The ambient temperature was predicted to rise at a slow pace like 2-3 degree Celsius in one thousand years earlier with the then human activities index on environment. But practically the human activities index is so high that it resulted in 4 degrees rise in 200 years only as per a recent report that is responsible for vanishing of glaciers in large scales from both poles and of polar temperature by more than 20 degree Celsius. Thus the present rate is so high that more than expected damage and change to environment is expected.Therefore we have to take advance and calculated steps to protect the environment. Please go through recent periodicals and updates to assess your predictions.
The greenhouse effect is the trapping of heat under the atmosphere, which is a natural effect caused by greenhouse gases. ... However, when greenhouse gas concentrations are too high, they trap too much heat and increase the temperature on Earth, causing the enhanced greenhouse effect.
