1. Aquaculture : raising fish in an artificial controlled environment

4. Long-lining : fishing technique that involves the use of long lines of baited hooks

5. Purse-seine fishing : fishing method that involves spotting a large school of fish, and then trapping them with a net

6. Trawling : fishing method that involves sending a giant scooping net to the ocean floor and bringing up everything it can

Explanation:

1. Aquaculture or aqua-farming is the process of raising fishes in an artificial controlled environment, a contrast to commercial fish farming.

2. By-catch are the unwanted fishes that are inadvertently caught in the process of fishing, and are often discarded.

3. Drift net fishing is a fishing technique that involves dragging long nets behind a boat and bringing in huge numbers of fish, without the need to anchor the nets to the bottom.

4. Long-lining is a form of fishing technique that involves the use of long lines of baited hooks, attached at intervals. It is mostly a commercial technique of fishing.

5. Purse-seine fishing is a fishing method that involves spotting a large school of fish, and then trapping them with a net called a seine. The nets hang vertically in the water while the bottom is held by weights.

6. Trawling is a fishing method that involves sending a giant scooping net to the ocean floor and bringing up everything it can to one or more boats.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
