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:
Freeeze-thaw weathering
Explanation:
Freeze- thaw weathering involves the breakdown of rock particles into smaller fragments through continuous fluctuations in the temperature of the water bodies. This form of weathering is common along coastlines. The water enters the rocks and then freezes when there is a decrease in temperature. The freezing expands the rock particles and aids frictions between the rock parts. This helps in the breakdown of the rocks to smaller particles.
It involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines
I would probably go with A because judging from the map it looks like most of it is mountains. <span />
Answer:
First determine the integers the x-coordinate and the y-coordinate are between. Then look at each to decide which integer the x- or y-value is closer to, and approximate the coordinate value to the tenths place.
Explanation: Sample Response on Edge
Unlike many other arts in western and central Africa, pottery typically is done by women. African potters were used for different purposes from decorative to culinary reasons. The pots were created differently depending on the origins of their different traditions and associated dietary and religious customs.
