Why it would be easier for geologists to study extrusive igneous rocks than intrusive igneous rocks?
Since extrusive rocks are formed by lava (not magma), the rocks can be found easier because they are on the surface, whereas intrusive rocks are formed underground so they are either harder to get to or they are found in smaller quantities.
Why is it easier for you to correlate diagrams than it is for geologists in the field to reconstruct a sequence of events?
It is easier to correlate diagrams because all units are scaled down, making it easier to see the "whole picture". In the field, the geologists have to deal with huge tracts of land, which makes it difficult to reconstruct a sequence of events.
Why are geologists interested in outcrops and cliffs?
In outcrops and cliffs it is possible to see multiple layers of rock exposed in one place, which makes it easier to study a set of rocks.
What does not affect the type of igneous rock that forms?
The time of day. The list is endless. It would be far easier to answer the opposite question. It IS affected by mineralogy, cooling time and a little by pressure.
What map would contour lines be easier to read a topographic map of a city or wilderness area?
it would be easier on a topographic map because it is easier to read

Why would it be easier for geologist to study extrusive igneous rocks than intrusve igneous rocks?
It's not necessarily easier to study extrusive versus intrusive rocks, simply because it depends on the exposure. In places like Hawaii, Iceland, Chile, and Yellowstone, where you have a great deal of geologically recent volcanism, it is very easy to study recent lava flows, and so in these places, it is easy to study extrusive igneous rocks. However, there are many places on the planet where granite, a classic example of an intrusive igneous rock, is exposed at the surface, so there is little difficulty in studying the intrusive igneous rocks at these locations.
Would a rock with no mineral crystals be called a intrusive?
No, but it's easier to see if you reverse the logic of the question. Intrusive rocks are igneous by definition, and these are all blends of crystalline minerals.
Why are some intrusive rocks be left behind when rocks are worn away?
Intrusive rocks come into other rocks in a molten state and when they cool they are frequently very hard with interlocking cemented crystal structures. When erosion occurs it is easier for wind, ice and rain to wear down the rocks into which the igneous rocks were intruded than the hard igneous rocks themselves. This leaves the igneous rocks sticking up (like King Arther's Seat in Edinburgh or the Tours of Dartmoore) as prominent features.

Which rock would be harder to break with a hammer a sedimentary rock or an igneous rock?
You would normally think that an igneous rock would be harder to break. However, it completely depends on which igneous rock is being compared to which sedimentary rock, as their resistance to breakage is so varied. There are some igneous rocks (obsidian and pumice, for example) that would break much easier than some sedimentary rocks, such as chert or flint.
Why are igneous rocks the best type of rock sample for radiomertic dating?
Because when they form, minerals in igneous rocks often contain only a parent isotope and none of the daughter isotope. This makes the isotope percentage more accurate and easier to interpret.
Why geologists are interested in outcrops or cliffs?
Geologists would be interested in outcrops and/or cliffs because sometimes cliffs show the different beds of rock under the Earth's surface. This is easier than drilling into the ground and getting a sample of the rocks.
