<u>Explanation:</u>
Cirque is a depression or a valley-like formation developed from the erosion of the glacier. They are formed in the mountain ranges. The slopes are steep and melted ice flows down to the floor.
The floor of a cirque is a bowl-shaped structure. The ice from all the sides from melting glaciers fill in the floor. When the glacier melts and slides the sides of the cirque, the floor converts into a lake. This small lake is called a tarn.
Answer:
A. Continental crust is less dense than oceanic crust.
Explanation:
Earth's crust can be divided into two categories, oceanic and continental. More of the surface is covered by oceanic crust, but because ocean crust is thinner than continental crust, the volume of the latter is significantly greater.
Oceanic crust is also denser than continental crust as it is made up of basaltic rock, whereas it's continental counterpart contains a type of less dense rock called felsic.

Answer:
1.6 million square km
Explanation:
The Great Pacific Garbage Patch is an excellent proof of how much the humans are damaging the environment, and how little they actually care about it. The biggest ocean on the planet, the Pacific Ocean, has a garbage patch that is estimated to be 1.6 million km in size. To put into a perspective, that's approximately twice the size of Texas. That data is from 2015 though, so the chances are that in the present the garbage patch is even bigger. The Great Pacific Garbage Patch comes to literary be a slow moving island of garbage. It is around 3.5 meters deep, and it contains around 7 million tons of garbage, the majority of which is plastic. This garbage patch actually has so much plastic that it outnumbers the plankton in the Pacific Ocean. The fish that lives around it, as well as the other marine life, are badly affected, and around 8% of them actually have plastic in them because of it.
