Multiple choice

What is the geological formation typically used for carbon storage?

  1. Depleted oil and gas reservoirs

  2. Deep saline aquifers

  3. Unmineable coal seams

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Carbon storage can be achieved in various geological formations, including depleted oil and gas reservoirs, deep saline aquifers, and unmineable coal seams. These formations provide suitable conditions for CO2 injection and long-term storage.

Multiple choice

Which geological formation is commonly used for storing CO2?

  1. Depleted oil and gas reservoirs

  2. Deep saline aquifers

  3. Unmineable coal seams

  4. Basalt formations
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Depleted oil and gas reservoirs offer a suitable storage option for CO2 due to their existing infrastructure, well-characterized geology, and the potential for enhanced oil recovery.

Multiple choice

What is the most common geological formation used for storing captured carbon dioxide?

  1. Basalt rock formations

  2. Sandstone formations

  3. Limestone formations

  4. Shale formations
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sandstone formations are often used for storing captured carbon dioxide due to their high porosity and permeability, which allow for the easy injection and storage of the gas.

Multiple choice

Which of the following is NOT a common type of rock?

  1. Igneous

  2. Metamorphic

  3. Sedimentary

  4. Artificial
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Igneous, metamorphic, and sedimentary are the three main types of rocks that occur naturally on Earth. Artificial rocks are not naturally occurring and are typically created by humans for specific purposes.

Multiple choice

What is the primary mineral component of granite?

  1. Quartz

  2. Feldspar

  3. Mica

  4. Pyroxene
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Granite is an igneous rock that is composed primarily of quartz, feldspar, and mica. Quartz is the most abundant mineral in granite, typically making up more than 50% of the rock's volume.

Multiple choice

Which of the following is NOT a type of sedimentary rock?

  1. Sandstone

  2. Limestone

  3. Shale

  4. Igneous rock
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Igneous rocks are formed from the cooling and solidification of molten rock. Sedimentary rocks are formed from the accumulation and compaction of sediment.

Multiple choice

Which of the following is NOT a type of metamorphic rock?

  1. Slate

  2. Marble

  3. Gneiss

  4. Granite
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Granite is an igneous rock, not a metamorphic rock. Metamorphic rocks are formed when existing rocks are subjected to extreme conditions that cause them to change their mineral composition and texture.

Multiple choice

Which of the following is NOT a type of karst feature?

  1. Caves

  2. Sinkholes

  3. Stalactites

  4. Sand dunes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sand dunes are not karst features. They are formed by the action of wind, not groundwater.
