Primary, Secondary & Tertiary Effects
100

The process which breaks down or dissolves of rocks and minerals on the surface. It can be physical or chemical. 

Weathering

100

A mixture of hot, fragmented solids and expanding gases. These heavier-than-air flows, race down the sides of a volcano much like an avalanche.

Pyroclastic flow

100

The majority of earthquakes occur around here. 

The ring of fire. 

100

True/False. A tsunami is a secondary effect caused by the primary effect of an earthquake. 

True

100

A primary effect of an earthquake is. 

Ground shaking, building collapses.

200

The process of sediment carried by wind, flowing water, the sea or ice coming to rest and sometimes forming a new landform. 

Deposition

200

Rock fragments and particles released by a volcanic eruption. 

Tephra

200

The name of the plates that are continuously moving and cause earthquakes are called. 

Tectonic plates

200

By building a tsunami sea wall, would it be a positive for society, the economy or the environment? 

Society 

200

A secondary effect of an earthquake is. 

Power outages, loss of life, tsunamis, landslides etc. 

300

The process whereby materials such as soil and rocks are worn away and transported by natural forces such as wind or water. 

Erosion

300

Rain that is made up of highly acidic water droplets due to air emissions, specifically high levels of sulphur and nitrogen.

Acid rain
300

The tectonic plate boundaries that move towards each other are called. 

convergent plate boundaries

300

Would the planting of tree-covered hills to mitigate the effects of a tsunami be beneficial to the society, economy or environment? 

Society & environment

300

A tertiary effect of an earthquake is. 

Homelessness, water contamination, medical expenses, mental health issues etc.

400

A coastal landform formed by deposition of material. 

Spit

400

A destructive mudflow on the slopes of a volcano.

Lahar

400

The tectonic plate boundaries that move away from each other are called.

Divergent plate boundaries. 

400
True/False. The flooding of an area caused by a tsunami is a tertiary effect. 

False

400

A primary effect of volcanos are.

Tephra, pyroclastic flow, lava flow

500

A landform which has a flat top and is elevated above the surrounding area with steep slopes or cliffs on some or all of the sides. 

Plateau 

500

This is a strategy to protect people in low-lying areas from pyroclastic flows.

Evacuation siren, evacuation route and education.

500

The most dangerous places to live in the world are.

Japan, Philippines or Indonesia.  

500

True/false. The primary effect is what is a direct impact of the natural disaster. The secondary effect is what is the cause of the primary effect, and the tertiary effect is the long-term impacts. 

True

500

A secondary effect of volcanos are.

Acid rain, lahars, earthquakes, loss of life
