The density of an object or quantity of matter is its mass divided by its volume. ... Non-standard conditions can result in a change of volume, affecting the density of the materials. Also, certain temperatures and pressures can result in a change the state of the matter, which also affects the density.
Answer:
1km
Explanation:
A scale of 1:25,000 means that 1 meter on the map equals 25,000 meters on the ground.
So,
Converting 4cm to meter;
4cm/100 = 0.04m
If;
1m = 25,000m
0.04m = ?
25,000 * 0.04 = 1000m
Answer:
Global Climate change
Climate is the general weather conditions of a place over many years. Climate change is a significant variation of average weather conditions. i.e., conditions becoming warmer, wetter, or drier over several decades or more. It’s that longer-term trend that differentiates climate change from natural weather variability. Although climate change and global warming are often used interchangeably, global warming is the recent rise in the global average temperature near the earth’s surface is just one aspect of climate change.
The effects of global climate change on earth's climate are as follows:
1. Extreme weather condition
2. Air Pollution
3. Health risks
4. Rising seas
5. More acidic, warmer oceans
6. Imperiled global ecosystem
Explanation:
The effects of global climate change
World Economic Forum’s 2016 Global Risks Report, reported that the failure to mitigate and adapt to climate change will be “the most impactful risk” facing communities worldwide in the coming decade ahead even of weapons of mass destruction and water crises. Blame its cascading effects: As climate change transforms global ecosystems, it affects everything from the places we live to the water we drink to the air we breathe.
