This question is incomplete because the options are not given; here is the complete question:
Which phrase describes a sill?
A. Fills in valleys and rivers
B. Is a hardened magma intrusion
C. Cuts vertically through older rock layers
D. Is built up by numerous eruptions over thousands of years
The correct answer is B. Is a hardened magma intrusion
Explanation:
Sills are horizontal layers in the soil that form as a result of magma. Also, sills are considered sheet intrusion because the hardened magma gets into older rock layers or soil layers and cuts the rocks horizontally. Moreover, the type of intrusion is studied by geologists to understand the formation and age of soil layers and this differs from other intrusions due to its composition and horizontal formation. According to this, the correct answer is B.
Answer:
Mid latitude cyclone are low pressure regional cyclone system formed in 30 to 55 N or S. In this region continental polar and tropical air masses collide to form fronts. Fronts are the boundary between two air masses. This front pushes the warm air to the north and cold air to the south and generating a clockwise rotation. Cyclone starts to form from southwest and reaches mature stage to form a well developed cold front and warm front.This cyclone become weak, both cold and warm front merge as occluded front, this causes the snow and poor weather condition in northeast US, same time southwest is the formation zone, so mild temperature.
I'd have to say gas because it usually doesn't change at all
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
- the elevation is increasing from southeast toward northwest
- the difference in elevation between the contour lines is 20 m
- the difference in elevation between the main contour lines is 100 m
Point X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

The first map shows colonized nations in 1945. European powers had colonized vulnerable and faltering nations to undergird their economies. The second map shows that, even more than 50 years later, the majority of moderately developed or underdeveloped nations were former colonies of the presently highly developed nations. This conclusion supports neocolonialism in that former colonies have moved toward industrialization and economic independence. The economies of the former colonies are still, to an extent, dictated by, and even hampered by, their former colonizers.
