What makes the sides of the river taller to prevent flood damage? what control the flow of water from major rivers? what instrument used to warm people of earthquakes and incoming tsunamis? what method used to hold sand dunes in place? what method of plowing and planting on sloped land that slows the runoff of rainwater?

Levees make the sides of a river taller to prevent flooding.

Explanation:

Levees are artificial walls erected at the sides of a river to prevent overflow.

Rivers overflow seasonally leading to flooding of the nearby places.

Floods from rivers lead to destruction of valuable property and loss of lives.

In order to control flooding and avoid this problem, water from rivers is prevented from overflowing using levees.

Flow control structures.

Explanation:

Water flow from rivers is controlled using flow control structures.

Some of this structures are:

Weirs

Flow splitters

proprietary-design devices

Water flow control is geared towards avoiding floods.

Water flow control also aims at taking advantage of flood water to conduct irrigation.

Water from major rivers is controlled to prevent disaster and also for economic use as said earlier.

Deep-ocean tsunami detection buoy

Explanation:

Deep tsunami detection buoys are devices used in early detection of the sea floor earthquakes leading to tsunamis.

The device observes the rise and fall of sea levels out in the sea.

This device allows for early detection of Tsunamis to avoid loss of property and lives from tsunamis.

The records of this device are relayed to an inland tsunami warning center.

Wooden sand fences

Planting vegetation

Foot paths

Explanation:

Sand is easily carried away by wind water and other agents.

In order to hold in place sand dunes in a bid to stabilize them, multiple of methods are used.

Wooden sand fences prevent sand from being carried away thereby holding the sand dunes in place.

Vegetation also prevents the sand that make up sand dunes from being carried away by wind or water.

Footpaths prevent loosening of the sand by footsteps.

Contour planting and plowing

Explanation:

Contour planting and plowing is the practice of plowing or planting along the contours.

During heavy rains, water running down the slope might lead to erosion.

Planting and plowing along the contours helps avoid erosion from run off and rain water by slowing down the speed of water down the slope.

Eroded soil is also held by the contours or the vegetation along the contours.

the correct answer is "c": the pillars proclaimed his regret at the bloodshed at the battle of kalinga and his conversion to buddhism.

the kalinga war is considered as one of the largest battles in the history of india. it was fought between the between the maurya empire, which ruled the lands of what is now known as india at the time, and the independent feudal kingdom of kalinga.

the army of maurya empire, led by its king ashoka, fought a prolonged war against kalinga. the war ended around 262 bce with the victory of the maurya empire. it is believed that ashoka, after having witnessed the loss of many lives during this war, felt deep responsibility and eventually converted into buddhism.

no because it could make the world a terrible place to live in.
