Constructive and Destructive Forces

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up landforms, such as mountains and valleys, through activities like volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion and weathering, which can be caused by water, wind, and ice.

Front

How do ocean waves contribute to erosion?

Back

Ocean waves can wash away rocks and soil along the shore, gradually reshaping the coastline.

Front

What role do tectonic plates play in mountain formation?

Back

Tectonic plates can push against each other, causing land to rise and form mountains over millions of years.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

How can plant roots cause weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart over time.

Front

What is a seismograph?

Back

A seismograph is an instrument that measures and records the motion of the ground during an earthquake.

Front

What information can seismographs provide about earthquakes?

Back

Seismographs can provide information about the strength and duration of an earthquake.

Front

What is the difference between constructive and destructive forces?

Back

Constructive forces build up landforms, while destructive forces break them down.

Front

What is an example of a constructive force?

Back

An example of a constructive force is a volcanic eruption that creates new land.
