D. the earth is not on the line of nodes
We can draw the conclusions that the rock is sedimentary rock due to it's feature that is formed by different rocks, and from the round pebbles we can deduce that the rock is a conglomerate
Answer:
There are 3 unique triangles that can be drawn with interior angles measuring 40º, 40º and 100º.
Explanation:
We should remember that according to Euclidean geometry the sum of internal angles in every triangle equals 180º and that every angle is opposed by a side. Given the values of internal triangles, the possible combinations are described below:
, 
, 
There are 3 unique triangles that can be drawn with interior angles measuring 40º, 40º and 100º.
Answer:
A. Rock is heated near the core at Point A, and therefore becomes less dense. It rises towards Point B. As it moves from Point B to Point C, it is cooled and becomes denser, so it sinks at Point D.
Explanation:
The process illustrated is a convection current, something seen places like the earth's mantle and atmosphere. The hotter matter gets, the more excited its molecules become and the more they become expanded and distant from each other. (Bear in mind that there is the same amount of matter but it takes up more space, i.e. less dense). This is because the molecules are excited by the thermal energy and bounce off each other, pushing them apart.
Cold, closer to the surface (or outer space in terms of air), in turn causes the matter to shrink back into itself, which leads to the increase in density that causes it to sink and repeats the process.
