Government surveillance can expand through events like the USA PATRIOT Act post-9/11, which broadened surveillance powers for national security. Conversely, it can shrink with rulings such as the 2015 USA FREEDOM Act, which curtailed bulk data collection by the NSA. Additionally, public outcry and legal challenges against invasive practices, exemplified by the backlash against the Snowden revelations, can lead to reforms that limit surveillance. Overall, the balance between security and privacy continues to shift based on political, social, and legal influences.
Expanding
The word would be expanding.
your eye's pupils expanding in the dark and shrinking in the light
It isn't as far as I know. If anything it is slowly shrinking as it cools over the millennia.
it means that the circle is either shrinking or expanding as time goes on
No one knows..it could have been just black and 'nothingness' sort of, or some people think that the big bang is like a heart, it keeps 'beating' or 'breathing' by expanding then shrinking then expanding then shrinking etc
The motto of International School of Communications is 'Shrinking Borders, Expanding Communities.'.
In general: expanding while melting; except for ice to liquid water, this volume is shrinking!
No they don't.
The Pacific Ocean is shrinking due to subduction, where one tectonic plate is being forced beneath another. This occurs at convergent plate boundaries where plates are moving towards each other. The Atlantic Ocean is expanding due to seafloor spreading, which happens at divergent plate boundaries where plates are moving away from each other, creating new oceanic crust.
The Pacific Ocean is not expanding in the traditional sense. However, tectonic plates beneath the ocean are constantly moving, which can lead to the ocean floor spreading in some areas due to seafloor spreading along mid-ocean ridges.
The Earth's plates were caused by natural reasons and cannot be explained. Scientists think that the plates were formed as a result of Earth first expanding as it was heated in the Great Bombardment and then shrinking as it cooled.
