Eruptions emitted through elongate cracks at the surface, as opposed to through the vents of volcanic cones, are termed ________
Elza [17]

Answer:

Fissure eruptions

Explanation:

A fissure vent or eruption fissure is a linear volcanic vent from which lava erupts mostly without explosive activity. The vent is usually not very wide but can be very long stretching for miles. While they do not explode like many volcanic cones do, fissure vents can cause large flood basalts. After some time the eruption builds up spatter cones and may concentrate on one or some of them. Spatter cones are steep-sided hills that consist of welded lava fragments that are called spatter and these cones form around vents.

If you compress geologic time into a single year, how much time has elapsed since Columbus arrived in the New World?
Readme [11.4K]

Answer: 3.6 seconds

Explanation: Geologic time is a way of measuring time based on events in the history of the Earth. If we compress this into one year, a single geologic year equals 4.6 billion years because the planet  was formed 4.6 billion years ago.  

Columbus arrived in the New World in August 1492, 528 years ago.

If 4.6 billion years = 1 year in geologic time,

528 years = 528 X  \frac{1X365daysX24hoursX60minutesX60seconds}{4600000000}

=3.6 seconds

<em>(I broke the year down into seconds by breaking it down into days, then hours, minutes and seconds because the value is very small)</em>

<em />

<em>So, if we compress geologic time into a single year, only 3.6 seconds have elapsed since Columbus arrived in the New World</em>

iren2701 [21]

Answer:

option (c) 14.7 lbs

Explanation:

Data provided in the question:

Area of the column = 1 square inch

Now,

we know Air pressure at the ground surface level from the atmosphere

= 14.7 Psi

also, it can be represented as

14.7 Psi = 14.7 pounds per square inch

Therefore,

Weight of the air weigh within a column that is 1 square inch in area

= Air pressure × Area

= 14.7 pounds per square inch × 1 square inch

= 14.7 pounds i.e 14.7 lbs

Hence,

The answer is option (c) 14.7 lbs
