Landforms and Processes - Gr. 10

Geomorphology is the scientific study of landforms and the processes that shape them.

• True
• False

Answer explanation

TRUE. Geomorphology is indeed the study of landforms and the processes that shape them, including natural forces like erosion, tectonic activity, and weathering.

Dunes are landforms created by water erosion.

• True
• False

Answer explanation

FALSE. Dunes are landforms created by wind action, not water erosion. They are typically composed of sand and formed in arid or coastal regions.

Orogeny is the result of tectonic plate movements and leads to the formation of mountain ranges.

• True
• False

Answer explanation

TRUE. Orogeny refers to the process of mountain formation resulting from the movement and collision of tectonic plates.

A mesa is an elevated landform with a flat top and steep sides, typically surrounded by a cap rock.

• True
• False

Answer explanation

TRUE. Mesas are elevated landforms characterized by flat tops and steep sides, often capped by a resistant rock layer.

Remote sensing involves direct contact with surfaces or objects to observe and study them.

• True
• False

Answer explanation

FALSE. Remote sensing is the observation of surfaces or objects without direct contact, typically done using satellites or sensors.

Valleys are usually carved by tectonic activities or natural disasters.

• True
• False

Answer explanation

FALSE. Valleys are often carved by erosional forces such as rivers, glaciers, and wind, rather than tectonic activities or natural disasters.

Loess is a silt-sized sediment created by the accumulation of windblown dust.

• True
• False

Answer explanation

TRUE. Loess is a sediment composed of fine silt-sized particles, formed by the accumulation of windblown dust.

Plateaus are typically formed by the accumulation of sediments from rivers.

• True
• False

Answer explanation

TRUE. Plateaus can be formed by the accumulation of sediments from rivers or through geological uplift and volcanic activity.

The Himalayas are the world's highest mountain range and are primarily found in South America.

• True
• False

Answer explanation

FALSE. The Himalayas are indeed the world's highest mountain range, but they are primarily located in Asia, not South America.

Mountain ranges outside the Pacific Ring of Fire and the Alpide Belt include the Arctic Cordillera in Antarctica.

• True
• False

Answer explanation

FALSE. The Arctic Cordillera is located in the Canadian Arctic Archipelago, not Antarctica. Antarctica is a separate continent with its own geological features.
