Answer:
b. silica
Explanation:
The majority of the volcanoes that form at subduction zones, or convergent plate boundaries, are stratovolcanoes. These volcanoes are also called composite volcanoes. The stratovolcanoes are known to have high to intermediate silica content of the lava they release. The eruptions tend to be periodic, and they are explosive and effusive in general, though there are exceptions. The fact that the lava is high to intermediate in silica content means that the lava is medium to highly viscous. Because of this, the lava tends to trap the gases in it, and as it reaches the surface and the temperature and pressure sharply change, the gases explode, resulting in eruptions that have lot of explosions and propelling of pyroclastic material.
In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
Similarities
- both contain H and O
- both are compounds , (different types of atoms)
- both are formed from covalent bonds and non metals
The country in Europe that has marine west coast climate is Ireland
Explanation:
The marine west coast climate is one of the major climate types according to Koppen's climate classification. This climate type is mostly dictated by the sea. In Europe, the marine west coast climate can be found in a surprisingly high latitude, and the main reason for that are the warm ocean currents. The warm ocean currents of the Atlantic are running along the western coast of Europe, and they manage to have huge influence on the climate of the region.
- This climate type can be found at lower elevations and hills in Western Europe.
- The climate is warmer than it should be considering the latitude where this climate type is found in Europe.
- The summers are mild to warm, the springs and autumns mild to cold, while the winters are cold.
- The temperature extremes in both winter and summer are usually absent, and the climate is much more balanced.
- There is high amounts of precipitation throughout the whole year.

Answer:
you will see contour elevation numbers. This is the elevation of the contour line, relative to mean sea level. Contour lines that are relatively close together indicate a slope that is fairly steep.
