Earth Sciences

Yes, soil is considered a renewable resource because it can be replenished through natural processes such as decomposition and erosion. However, it can also be depleted through factors like erosion and pollution, so sustainable management practices are important to maintain its renewability.

Yes, stone is considered a type of rock.

Styrofoam is generally considered worse for the environment than plastic because it is not biodegradable and can take hundreds of years to break down, leading to long-lasting pollution. Plastic, while also harmful, can sometimes be recycled or biodegrade more quickly.

Yes, the Dead Sea is very salty.

Yes, the Earth is losing water due to factors such as evaporation, human consumption, and climate change.

No, the Sun is older than the Earth.

Photosynthesis is considered a carbon sink in the ecosystem because it removes carbon dioxide from the atmosphere and stores it in plants as carbohydrates.

Yes, positive lightning is generally considered more dangerous than negative lightning because it is typically stronger and carries a higher voltage. Positive lightning strikes also tend to occur less frequently but can cause more damage and pose a greater risk to individuals and structures.

Relative humidity and humidity are related but not the same. Humidity refers to the amount of water vapor in the air, while relative humidity is a measure of how much water vapor the air is holding compared to the maximum amount it could hold at a given temperature.

No, rock is not a renewable resource because it takes millions of years for rocks to form through geological processes. Once rocks are mined or extracted, they cannot be easily replaced within a human lifetime.

Yes, sandstone is classified as a chemical sedimentary rock because it is formed from the accumulation and cementation of mineral grains, such as quartz, that have been transported and deposited by water.

Yes, silt is smaller than sand.

Soil is considered a renewable resource because it can be replenished over time through natural processes like decomposition and weathering. However, it can also be depleted faster than it can be replenished through activities like deforestation and unsustainable farming practices.

Yes, limestone is a carbonate rock composed mainly of the mineral calcite, which is a form of calcium carbonate.

Magnetite is classified as a mineral, not a rock.

Magnetite is classified as a mineral, not a rock.

No, n2 (nitrogen gas) is not considered an air pollutant.

No, new water is not created in the natural water cycle. The water on Earth is constantly recycled through processes like evaporation, condensation, and precipitation.

Yes, nitrogen dioxide is considered an air pollutant.

Yes, the ozone layer is thinning due to human activities releasing chemicals like chlorofluorocarbons (CFCs). The potential consequences include increased UV radiation reaching Earth, leading to higher rates of skin cancer, cataracts, and harm to marine life and ecosystems.

Yes, ozone is considered a greenhouse gas because it traps heat in the Earth's atmosphere, contributing to the greenhouse effect.

Oil is not directly made from fossils. Instead, oil is formed from the remains of ancient plants and animals that were buried and subjected to high pressure and heat over millions of years. This process transforms the organic matter into hydrocarbons, which make up crude oil.

Yes, some people believe that global warming may have positive effects on the planet, such as longer growing seasons and increased agricultural productivity. However, the majority of scientists and experts agree that the negative impacts of global warming, such as rising sea levels and extreme weather events, far outweigh any potential benefits.

Yes, the aurora borealis is not dangerous to humans. It is a natural light display in the Earth's sky, typically seen in high-latitude regions.

Yes, it is unusual to experience winter in July.
