Answer:
One
Explanation:
Even though Finland and North Korea are thousands of kilometers away from each other, with Finland being in Northern Europe, and North Korea in East Asia, there's only one country between them. The only country that separates these two countries is the largest in the world Russia. Finland of course borders the European, much more developed part of Russia, while North Korea borders the eastern part of Asian Russia, practically Siberia, which is much less developed. These countries are totally different from one another in every aspect, be it politically, socially, economically, geographically, climate etc.
C multiple choice no problem
Answer:
10 meters
Explanation:
A wave is a natural phenomenon that travels through a material medium but does not have a permanent effect on the particles of the medium. It can either be electromagnetic or mechanical. The propagation of a wave can be represented by a sinusoidal graph, which has crests and troughs.
A crest is the point of maximum displacement, while trough is a point of minimum displacement. The distance between two crests or troughs gives the wavelength of the wave.
From the question, the horizontal distance between a crest to the next trough is 5 meters which is half of the wavelength.
Thus wavelength = 5 × 2
= 10
The wavelength is 10 meters.
B. Subduction
Explanation:
Subduction is one of such processes that causes thick sequences of sedimentary layers to accumulate along the boundaries of continental and oceanic plates.
- Continental and oceanic plates meets at a subduction zone which is a convergent margin.
- At this zone, the dense oceanic plate subducts or dives into the weak and less dense asthenosphere below.
- As it subducts, the ocean floor sediments on top is peeled off and the slab of lithosphere pulls down.
- This causes an accretionary wedge between the two zones.
- Most the sediments will eventually get metamorphosed into a metamorophic rock.

Answer:
C. Magma from venus mantle erupted as lava.
Explanation:
A volcano is a landform which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.
From the little description given, option C gives the best scientific explanation to the occurrence of the volcano on the surface of Venus. For a planet like venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.
It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.
Evaluating other options:
... Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.
.... If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.
.... Heat is not enough to from volcanoes. Other factors are also in play.
