Answer:
Carbonate sedimentary rocks
Explanation:
Carbonate sedimentary rocks are the rocks that are primarily comprised of carbonate minerals such as calcite or aragonite. They are formed chemically. These rocks are formed when Carbon is initially trapped with the accumulation of sediments over it in association with fossil shells. They are also formed due to the dissolution or precipitation by groundwater, depending upon the temperature, pH and dissolved ions present in the solution.
They are often marked by the presence of karst topography and caves.
Some examples of these rocks are limestone and dolomite.
Sunday, July 20, marked 45 years since the United States put the first two astronauts safely on the moon. The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment?
