Answer:

The volcano in question is a cinder cone volcano.

Explanation:

There are multiple types of volcanoes, and their types are determined by their formation, appearance, and eruptions, which are actually all related to one another. One of the types of volcanoes is a cinder cone volcano. This type of volcano is a short-lived volcano that actually occurs at the flanks of other types of volcanoes, forming from the larger vents of the preexisting larger volcanoes.

As mentioned, the cinder cone volcanoes occur near other larger volcanoes. When the larger volcanoes have bigger eruptions, the vents propel a lot of magma toward the surface, resulting in the formation of a cinder cone volcano. Because they emerge very quickly and how they erupt the material they have very steep sides. Because of their eruptions that shoot-out thick blobs of lava that fall as cinders they got the name cinder cone volcanoes.

4. Describe the law of cross-cutting relationships: _
vlada-n [284]

<u>Answer:</u>

<em>The rule of cross-cutting connections expresses that a volcanic interruption is constantly more youthful than the stone it cuts over.</em>

<u>Explanation:</u>

<em>Analyze the volcanic interruption and the encompassing rock.</em> Cross-cutting connections is a guideline of topography that expresses that the geologic element which cuts another is the more youthful of the two highlights.

It is a relative dating strategy in geography. The <em>standard of cross-cutting connections expresses that a volcanic interruption is constantly more youthful than the stone it cuts over.</em>

The measures of the three angles of a triangle are given by 18x − 7, 12x + 9, and 4x. What is the measure of the largest angle?
Goryan [66]

Answer:

The greatest angle is 18x-7

Explanation:

According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.

The given angles of a triangle are 18x-7,12x+9,4x

Therefore,

18x-7+12x+9+4x=180°

34x+2=180°

34x=178°

x=\frac{178}{34}=\frac{89}{17}

18x-7=18(\frac{89}{17})-7=\frac{1602-119}{17}=\frac{1483}{17}≈ 87.2°

12x+9=12(\frac{89}{17})+9=\frac{1068+153}{17}=\frac{1221}{17} ≈ 71.8°

4x=4(\frac{89}{17})=\frac{356}{17} ≈ 20.9°

Therefore, greatest angle is 18x-7

If the half life for strontium-90 is approximately 28 years, then what is the whole life for strontium-90?
sveta [45]
Set this up as

10 = 40 (1/2)t/28

and solve for t in years.

10/40 = (1/2)t/28

log(0.25) = (t/28) log(0.5)

t = 28 log(0.25) / log(0.5) years = 56 years

Test the answer:

56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
