Market economies are based on market forces like supply and demand. Mixed economies fall in the middle of market and command economies (where economic choices are governed by some central entity usually the government). The former Soviet Union (USSR) is an example of a command economy where economic choices (what to buy, sell and produce) where made by the government. If Australia is becoming more of a market economy and less of a mixed economy, fewer decisions are made by the government. Here's a diagram of two major types of economies:
Command Economy <-------------- Mixed Economy --------> Market Economy
(Government makes the decisions) (A little of both) (Individuals decide)
Floods! Floods don't really happen to much, but there was a big one which caused the land to become super moist. Which made it difficult to do Dry Farming. I hope this helped! :)
Answer:
The answer is "Provide strong evidence for seafloor spreading".
Explanation:
The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.
A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.
In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.
