Answer:
Basaltic magma -- SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na
Andesitic magma -- SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K
Rhyolitic magma -- SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na
Explanation:
The correct option is c. On Earth, we can see all its sides in the course of a month as it goes around us. This is false about moon.
The sole natural satellite of Earth is the Moon. With a diameter that is around one-fourth that of the Earth, it is the fifth biggest satellite in the solar system and the largest and also most massive when compared to its parent planet. The Moon is larger than any known dwarf planets of the Solar System and is a planetary-mass object with a distinct rocky body, rendering it a satellite planet according to geophysical definitions of the term. There isn't much of an atmosphere, hydrosphere, or magnetic field there. With a surface gravity of 0.1654 g, it has a gravity that is around one-sixth that of Earth. Jupiter's moon Io is the only satellite in the Solar System that is known to have a higher gravity and density.

Answer:
- shows isobars
- was probably used by meteorologists
Explanation:
The map that is show was a map that was probably made and used by meteorologists. It is a map that that shows isobars, thus it is a map that represents the air pressures across the US and Canada. We can see the air pressure zones, some of which high, some of which low. These maps are often used when the weather information is concluded about certain areas, as the air pressure is directly connected with the temperature, and the movement of the air masses.
Answer:
The angles are the same.
This means that in a translation, the location and/or position of the object changes, but the angles and overall shape stay the same.
