Year 12 TAS Environmental Science practice questions
This public preview page identifies the planned Year 12 TAS Environmental Science demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
Sample-question focus
The planned public sample is for Year 12 TAS Environmental Science practice and will open after the demo questions are reviewed.
Skills covered
Practice Earth systems, pollution, biodiversity, sustainability, food and water security, climate change, energy use, and scientific inquiry.
Exercise and test mode
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Curriculum link
Compare this demo with the Tasmania Year 11-12 Environmental Science curriculum page to scan related topics, subtopics, and pathway coverage.
Sample TASC Year 12 Environmental Science questions
These sample questions are visible on the page before login. They show TASC Year 12 Environmental Science biodiversity change, climate evidence, carbon budgets, energy transitions, risk models, and environmental decisions with diagrams, graphs, transects, and decision tables before opening the demo.
TASC Year 12Environmental ScienceBiodiversityhardbiodiversity-index table
1. A biodiversity-index table shows restored site = 0.69 and unrestored site = 0.52. Which site has the greater index?
Choices
Restored site
Unrestored site
Both sites are equal
The smaller index is greater
Explanation:
The restored site has the higher biodiversity index.
TASC Year 12Environmental ScienceClimate evidencehardclimate-trend graph
2. A sea-surface temperature graph rises from 12.8 C to 13.9 C across the record. What change is shown?
Choices
An increase of 1.1 C
A decrease of 1.1 C
No change
An increase of 26.7 C
Explanation:
The change is 13.9 - 12.8 = 1.1 C.
TASC Year 12Environmental ScienceCarbon budgetshardcarbon-budget diagram
3. A farm carbon-budget diagram shows 92 t CO2-e emitted and 24 t CO2-e stored in shelterbelts. What is the net emission?
Choices
68 t CO2-e
116 t CO2-e
24 t CO2-e
92 t CO2-e
Explanation:
Net emission is 92 - 24 = 68 t CO2-e.
TASC Year 12Environmental ScienceWater qualityhardwater-quality graph
4. A dissolved-oxygen graph shows a river reach increasing from 5.0 mg/L to 7.4 mg/L after riparian planting. Which result is supported?
Choices
Dissolved oxygen improved.
Oxygen fell to zero.
The graph measures only carbon.
Riparian planting cannot affect water.
Explanation:
The after-restoration dissolved oxygen value is higher than the before value.
TASC Year 12Environmental ScienceCoastal fieldworkhardfieldwork transect
5. A shoreline transect shows erosion pins moving back by 0.12 m, 0.18 m and 0.21 m. Which site has the greatest retreat?
Choices
Site 3
Site 1
Site 2
All sites are equal
Explanation:
Site 3 has the largest retreat value, 0.21 m.
TASC Year 12Environmental ScienceEnvironmental managementhardsustainability matrix
6. A decision matrix scores wetland restoration higher for biodiversity but lower for upfront cost than a concrete drain. What is the main decision issue?
Choices
The options involve a biodiversity-cost trade-off.
Only the cheapest option has environmental value.
Both options have identical impacts.
Biodiversity is not a criterion.
Explanation:
The matrix shows different strengths across criteria, so the decision requires weighing biodiversity against cost.
For parents comparing TASC Year 12 Environmental Science support
TASC Year 12 Environmental Science practice should help students connect systems thinking to visible evidence: biodiversity change, climate evidence, carbon budgets, energy transitions, risk models, and environmental decisions. These examples preview that visual reasoning before the no-login Environmental Science demo.

In progress
Year 12 TAS Environmental Science is available to purchase, and the public demo preview is still being prepared.
Students can use the purchased subject once subscribed; this anonymous preview will be opened after the curated public question set is ready.
Does this page include Year 12 TAS Environmental Science practice questions?
Not yet. The Year 12 TAS Environmental Science demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
Can students try the demo without signing up?
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
How does this demo relate to curriculum coverage?
This demo is linked with the Tasmania Year 11-12 Environmental Science curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
