The quote states that we should be using solar energy before our limited amount of naturally occurring oil and coal runs out. Meaning; we should be proactively working towards solar power rather than to wait for our resource to run out to start.
Answer:
(A) It connects Western and Central Europe.
(C) It is an important trade route.
(D) It is used for transportation.
Explanation:
The Danube is a river in central Europe and the second longest in this continent (the first is the Volga), which flows mainly through ten countries (Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine) to finally flow into the Black Sea.
This river is of great importance for Eastern Europe because its channel serves as an international bridge for agricultural, fishing, tourism, commercial and industrial activities. In addition, the majority of the population that lives in its vicinity, depends on the water of the Danube to carry out its activities, which is why there is a large number of reservoirs and dams on its way.
Another important aspect is that the Danube has a high economic potential, due to its capacities for transport, commerce and tourism, so the use and use of its waters has been promoted.
Answer:
C. movement of the Earth’s plates
Explanation:
Volcanoes and earthquakes sometime occur in Canada's western ranges because of the movement of the Earth's plates.
- Plate tectonics is responsible for the volcanic activities which brings magma to surface from the asthenosphere.
- Also, earthquakes are products of plate tectonics.
- The differential movement caused sudden breakage of the plate and releases are sudden burst of energy.
Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground.
Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids. Drought, along with resulting high groundwater withdrawals, can make conditions favorable for sinkholes to form.
1-choose any two points on the line.
2-draw a right-angled triangle with the line as hypotenuse.
3-use the scale on each axis to find the triangle's: vertical length.horizontal length.
4-work out the vertical length ÷ horizontal length.
5-the result is the gradient of the line.
