Answer:
True
Explanation:
Magma is known as melted rock deep within the Earth, normally coming from the melting of the upper mantle or crust. Magma is formed by the partial melting of the mantle and crust and this can occur in different ways. One way can be called heat-transfer melting. Rising magma or rock will bring heat with it, and so can melt the surrounding mantle or crustal rock. For example, magmas generated in the mantle tend to be around 1200 degrees Celsius, whereas the more silicate minerals such as quartz and orthoclase feldspar (common in continental crustal rocks) begin to partially melt at around 650-850 degrees Celsius. Therefore, the crustal rock will begin to partially melt due to the introduction of heat from rising magma. A Another way of melting rock is known as decompression melting. During decompression melting, rock from within the mantle is brought to the surface adiabatically (no exchange of heat or energy with its surroundings) and so the lithostatic pressure decreases. This means that the parcel of rising rock crosses the solidus, and so at this point the thermal vibration of the molecules is no longer counteracted by the lithostatic pressure and the rock begins to partially melt.
Yes because it’s higher mass the higher it is, the more thermal energy gets absorbed
So the mass of water remains the same when it freezes. The mass of any substance is the same when it changes phase from liquid to gas, or solid. This is the principle of mass conservation.
Explanation:
There's a massive amount, just think of anything everyday. Like a table on the floor, or when your walking around and putting pressure on the floor. When you squeeze something which is solid. Anything like that will do.
<h2>Right answer: 8 m</h2><h2 />
When two waves propagate in the same medium, in the same or opposite direction, they <u>overlap (superposition</u>), that is, the individual waves are added producing a resultant wave. When the superposition of the waves occurs, they continue to advance after the encounter happens, conserving their properties, such as amplitude, frequency, wavelength and speed.
In this case, we have two water waves travelling in opposite directions with <u>differente amplitude</u>, when both waves encounter each other, at that moment the amplitude of the resultant wave is the sum of both, that is:
5m + 3m = 8 m
Therefore, the correct option is D
