droughts

this picture is a picture of the drought in aulstalia. they have had the lowest amount of rain fall in the last 3 mon, making it a drouht. If your thinking theat we have not had rain in the lasy 3 mon, that is true but we have other types of waether keeping our climate moist.The drought did not just effect hte people and the land, it also effected the animals. In 1902, the sheep population droped to 54,000,000 and the cattle droped 40%. It was 1925 untill the population of both were back up to normal.
During WW2, aulstalia suffured dry conditoins from 1937-1947. The longest drought ever recored in aulstalia was in alice springs and melbourne because alice spring is a very dry place and is very hot.
and in melbourne because they use to much water.

 This map shows the ares where the drought has been great.
the drought effects everythong when they hit. they hit because in humid, or wet, regions, a drought of a few weeks is quickly reflected in a decrease in soil moisture and in declining flow in streams. People who use water from streams in these areas may face water shortages as soon as streamflow begins to decline. In arid, or dry, regions, people rely on ground water and water in reservoirs to supply their needs. They are protected from short-term droughts but may have severe problems during long dry periods because they may have no other water source if wells or reservoirs go dry.

X-ray vision
1)milky way canter: it is the heart of the galaxy that host our earth and sun. the black hole is seen through engergetic emission
2)Quasar: an active black hole that takes in a mass amount of thingd in space. it out shines the rest of the galaxy

Radio waves
3)Moon: the moon is our friend. under radio waves it glows green yelow and red.
4)Saturn: under radio waves the planet looks red w blue and yellow rings.
5)the Sun: the sun is blue under this type of light. it has some red and green spots on it as well.

Cygnus
The star that is know as Cygnus is about 10,000 lightyears away from the sun. you have to go way out past  plutio and then some. this star is best seen in xray vision. it sucks gas in form surrrounding stras.

Andromeda
 Andromeda is a galaxy that is 1.000.000 lightyears away from the sun. in the middle of this spiral spinning  galaxy, is a massive black hole that is 30x stronger then our sun.

 How are black holes born?
A: a black hole is born when an object no longer can withstand the stranght of its own gravity.

What happens when two black holes collide?

A: it is possible for two black holes to collide, and when they do, they cant escape each others gravity. they emegre with each other and become one large black hole.

Do black holes obey the laws of gravity?
A: balck holes obey all laws of physics includding the laws of gravity. the reason they act this way is a direct cause of gravity.
