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.
Answer:
Continental drifting
Explanation:
Continental drifting talks about the movement of continents . The process was first discovered by Alfred Wegener. Alfred Wegener noticed the great similarities of the Atlantic coastline of Africa and the south America. He noticed the edge of each continents fits like a puzzle. The idea that the continents were once joined together and have split apart was born out of the observation of the similarities of the continents.
The similarities of fossil found in different continents also proved that the continental has been drifting . The similar fossils found in different continents were better explained if the continents were once joined together. Fossils like the Mesosaurus , a fresh water reptile were found in different continents.
The similarities in rock structure also proved the continents have been drifting .
Size hence streams are little and rivers are bigger than streams because a stream connects between two or more rivers

The correct answers are:
- increased greenhouse gases;
The transportation system is one of the biggest emitters of greenhouse gases into the atmosphere, and this is due to the combustion of the fossil fuels, the end result being huge amounts of CO2 released in the air.
- increased pollution;
The energy sources used for the transportation systems are in general very damaging for the environment as they are letting out as a side product lots of pollutants.
- Easy movement of people, products, and ideas;
With the development of the transportation systems, the movement around the globe has become very easy and quick, and that has contributed to constant communication between people from all over the world, exchanging goods, ideas, technologies, as well as migration.
