The high temperature in the interior of the earth may result in the formation of

Step 1: Analyze the question The question asks which feature forms because of high temperature inside the earth. So we need a feature caused by heat, not by pressure or tension in the crust.

Step 2: Explain the concepts

• Fold mountains form from compressional forces. Plate collision squeezes and buckles rock layers (e.g. the Alps and Himalayas).
• Horst is a block of land left standing when the land beside it drops along faults. It results from faulting caused by tensional or compressional forces.
• Rift valley is a block that sinks between two parallel faults, caused by tension or compression (e.g. the East African Rift).
• Geyser is a hot spring that periodically shoots hot water and steam into the air. Underground water is heated by hot rocks or magma deep in the earth. It turns to steam, builds up pressure, and erupts (e.g. Old Faithful in the USA).

Step 3: Solve

• Fold mountains, horsts, and rift valleys are tectonic (crustal movement) features. They are caused by forces that move the crust, not mainly by heat.
• A geyser depends directly on the high interior temperature heating groundwater. It is a volcanic or thermal feature.

Answer: C. Geyser

Tip: Link features to their cause:

• Heat → geysers, hot springs, volcanoes
• Compression → fold mountains
• Faulting → horsts and rift valleys

When you see "high temperature" in a question, think of hot water, steam, or magma features.
