Earth Science Homework Help

About Earth Science

Earth science covers the rocks beneath us, the processes that shape the surface and the atmosphere above it. In these questions it sits close to physical geography: rock types and the rock cycle, weathering and erosion, soil, plate tectonics, earthquakes and volcanoes, and the weather and climate systems that act on all of them.

Popular topics in Earth Science

• Rocks & The Rock Cycle

  Igneous, sedimentary and metamorphic rocks, how each forms, and the cycle that converts one to another.

• Weathering & Erosion

  Physical, chemical and biological weathering, agents of erosion, transport and deposition, and the landforms produced.

• Soil

  Soil formation and profiles, horizons, texture and fertility, soil erosion and conservation measures.

• Plate Tectonics

  Plate boundaries and their movements, continental drift evidence, fold mountains and rift valleys.

• Earthquakes & Volcanoes

  Causes, focus and epicentre, measuring magnitude, volcanic features and the effects on people.

• The Atmosphere

  Layers and composition, pressure and winds, humidity, clouds and rainfall types.

• Weather & Climate

  The difference between them, measuring elements of weather, climate regions and climate change.

• The Water Cycle

  Evaporation, condensation and precipitation, run-off and infiltration, drainage basins and the water table.

How ScanSolve helps with Earth Science

ScanSolve answers process questions as processes: the stages in order, with the agent and the condition each stage needs, which is what turns "explain how a rift valley forms" from a list into an explanation. Where a question asks for effects, the answer separates physical effects from effects on people, because syllabuses mark them separately.

Diagram and map questions are read before they are answered — contours, keys and scales — and where a sketch is expected the answer describes what to draw and label. Case-study questions keep the example concrete rather than generic.

Study tips for Earth Science

1. 01

   Learn processes as ordered steps, not as paragraphs. Marks are usually given per stage, in sequence.

2. 02

   Keep two or three real examples per topic (a named volcano, a named rift valley). A named example converts a general answer into a credited one.

3. 03

   Distinguish weather from climate in your wording. Examiners treat the mix-up as a knowledge error, not a slip.

4. 04

   For a landform question, say which agent is at work — water, wind, ice or gravity — before describing the shape.
