2. Impacts of global warming are distributed equally all over the planet.
3. in the poles
4. in the equator

Which gas was most abundant in the Earth's early atmosphere?

2. Carbon dioxide
3. Oxygen
4. Nitrogen

2. Nucleus
3. Cell wall
4. Vacuole

1. Animal cell
2. Plant cell

What is the term for all living organisms in an ecosystem?

1. Habitat destruction
2. Biotic factors
3. Abiotic factors
4. Population dynamics

What is the main cause of habitat destruction?

1. Climate change
2. Natural disasters
3. Human activities
4. Predator-prey relationships

What is the purpose of random sampling in biodiversity studies?

1. To count all individual organisms
2. To ensure a representative sample
3. To avoid studying small organisms
4. To study only the largest organisms

What is the process of studying a small area to estimate the number of organisms in a larger area called?

1. Ecological sampling
2. Ecosystem analysis
3. Biodiversity measurement
4. Population estimation

What is the term for a group of organisms of the same species living in the same area?

1. Biodiversity
2. Ecosystem
3. Community
4. Population

Which human activity can contribute to flooding?

1. Water conservation
2. Sustainable agriculture
3. Wetland preservation
4. Deforestation

When there is deforestation..

1. there is less interception and so the soil becomes saturated more quickly, this leads to surface runoff and the water will reach the river more quickly
2. more interception will happen, soil will have chance to infiltrate in the soil and flow to the river underground
3. there are more impermeable surfaces so no interception and more surface runoff and water reaches the river more quickly
4. the soil can be eroded and washed into the river which can decrease the amount of water that can be held in the river, meaning it will be more likely to flood

The way of life of many tribes is under threat due to what?

What are some natural sources of greenhouse gases?

1. Deforestation
2. Burning fossil fuels
3. Volcanic eruptions and decomposition of organic matter
4. Industrial processes

How do humans primarily impact the environment through the release of greenhouse gases?
