Answer:
Carbon dioxide; lower than.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.
Earth’s atmosphere helps to regulate its temperature. However, the addition of gases such as carbon dioxide causes more energy to radiate back toward Earth. As a result, the atmospheric temperature increases over time. If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun. This implies that the temperatures on Earth would be lower than Earth’s current temperature.
Answer: b. Clear-cutting
Explanation: Clear cutting is a cheap and effective way of harvesting trees or timbers, this methods helps the forest operators to get the best out of a forest at a very reduced cost.
Clear-cutting is bad because removing the whole tree from an area destroys outrightly the natural habitat of most widelife, and it will also lead to the destruction of the eco-system that relies on the forest.
Answer:
2. Sediment B quartz sand forms when rocks first break apart
Explanation:
- Limestone is a carbonate rock that sedimentary in origin that is often made up of skeletal body parts of freshwater organisms such as corals, and mollusks, etc.
- Major material of mineral calcite. That are different crystal forms of calcium carbonate CaCO3. It's colorless or white, also gray, yellow, green. And chemically dissolves to form an acid.
- Calcite may form in substance to the response of organisms which result in sulfate dependent and when methane is oxidized. They have existed on earth primarily in forms of calcium carbonate in marine waters low magnesium calcite.
