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.
The correct answer is - secondary economic activity.
The developing countries are trying to boost and develop their economies by developing the industry. They build lots of industrial facilities, factories, and instead of selling the raw materials to the more developed countries, they start to use the raw materials for their own purpose and manufacture them into products ready for the market. This production can include anything from creating steel from the iron ore, make juices from the fruits and vegetables, use the cotton for making clothes etc., so all in all making final products that directly end up on the market, thus making a bigger profit.
Location is determined by longitude and latitude.
