I would have to go with Europe.
This is known as the visible spectrum of electromagnetic radiation, or visible light. This is the frequency of light that we see, and which illuminates our world as it reflects off of objects. Compared to the full spectrum of electromagnetic radiation, the visible light portion is actually quite small.
Answer:
a. True.
b. False.
c. True.
d. True.
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, volcanoes, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
a. Plates shift the continents around as they move, so Earth's surface is constantly changing.
b. False: the contacts between plates are called passive margins. A passive margin is a region where continents have rifted apart and are then separated by a body of water such as an ocean.
c. True: plates may consist of both ocean floor and continental crust, but never just oceanic or continental crust.
d. True: there are 120 major tectonic plates.
Oil still plays an important role in the global economy despite the continued efforts to reduce its use and to find alternative green energy sources. In the early days, finding oil during a drill was considered somewhat of a nuisance as the intended treasures were normally water or salt. It wasn't until 1847 that the first commercial oil well was drilled in the Absheron Peninsula, Azerbaijan.1 The U.S. petroleum industry was born 12 years later, in 1859, with intentional drilling near Titusville, Pennsylvania. (Drilling in the United States began in the early 1800s, but they were drilling for brine so any oil discovery was accidental.)2
The answer is black holes. I hope this helps
