<h2>Answer is II and III</h2><h2 />

Explanation - Global warming is an increase in the surface air temperature of the Earth. Human activities such as the burning of fossil fuels are contributing to a current episode of global warming. Many scientists predict that current global warming will cause an increase in extreme weather conditions, such as flooding and drought.

Drought conditions limit the amount of water available to plants. Plants cannot live without sufficient water. On the other hand, too much water can cause excessive flooding, which can inhibit photosynthesis in plants if a plant's leaves and stems are submerged.

Increasing CO2 levels and increasing growing seasons are both positive effects that global warming could have on plant life on Earth.

Answer:

II. Global warming may cause drought conditions in some areas, which would limit the amount of water available to plants in those areas.

III. Global warming may cause severe flooding in some areas, which could inhibit photosynthesis if a plant's leaves and stems are submerged.

Explanation:

Global warming is one of the effects of climate change. It is simply the warming of the surface of the earth as result of increase in temperature on the earth surface.

Global warming results from increase in levels of greenhouse gases in the earth's atmosphere. These gases prevents radiation from leaving the earth surface thereby leading to increase in temperature. The more the gases, the more the spike in temperature.

This increase in temperature can lead to drought.

As the earth also warms, polar ice can melt which can increase the level of water in the world's oceans and then flooding of coastal areas.

WHAT WILL HAPPEN TO THE RESISTANCE OF CONDUCTOR IF :

Debora [2.8K]

Answer:

1. The length of the wire is halved.

the resistance of a conductor is directly proportional to it's length (L) as R - L. Thus doubling it's length will double it's resistance, while halving it's length would halve the resistance. Also the resistance of a conductor is inversely proportional to it's cross sectional area.

2. The area of cross-section of the conductor in increased.

On increasing the area of cross-section, resistance decreases. Thus is because resistance is inversely proportional to area.

3. The temperature of the conductor is increased.

With increasing temperature, the resistance of the wire increases as collisions within the wire increases and "slow" the flow of current... Since conductors typically display an increased resistivity with temperature increase, they have a positive temperature coefficient.

Part 1;

The answer is; Carbon dioxide. Approximately 0.8% of the atmosphere is composed of carbon dioxide. It is in the gaseous phase.

Part 2;

The answer is; Combustion. Human activity of burning fossil fuels increases the carbon dioxide in the atmosphere. This has a secondary consequence of warming up the planet because carbon dioxide is a greenhouse gas.

Part 3:

Carbon is conserved in the cycles mostly in plants. Plants take up carbon dioxide in photosynthesis and make organic compounds (carbohydrates). Therefore first acts as carbon sinks. Even the fossils fuels that we burn come from plankton that is major carbon sinks too.

Part 4;

Carbon dioxide in the atmosphere is created by several processes including combustion and respiration. All living things respire out carbon dioxide. Plants take up this carbon dioxide and sequester it. When animals feed on plants they release part of this carbon back to the atmosphere through respiration

Answer:

Sand has less specific heat than water.

Explanation:

Specific Heat is amount of heat needed per unit mass, to raise temperature by 1 degree celsius.

More specific heat means more heat energy needed to increase temperature. It implies - more time needed to absorb heat, increase temperature; and also more time needed to lose its heat.

Less specific heat means less heat energy needed to increase temperature. It implies - less time needed to absorb heat, increase temperature; and also less time needed to lose its heat.

Sand has less specific heat than water. So, it needs less heat absorption to increase temperature by per unit (celsius) ; than water. Hence, same level of heat to both sand & water ; increase temperature of sand more than water, & make it more hot.
