1. what is weather?
2.if you were a meteorologist, how would you describe today’s weather for your town?
3.what are 3 important things that our atmosphere does that allows for life on earth?
4.the local news mentions that we will have a warm front coming through nh this week. what might we experience for weather before, during and after this front passes?
4. is it possible that humans and dinosaurs have drank the same water? formulate an argument to this question using your knowledge of the water cycle.

The atmosphere blocks out harmful rays from the sun. The ozone layer, which lies in the stratosphere 11 to 50 kilometers from the Earth's surface, blocks out many harmful forms of radiation. Without the ozone layer, ultraviolet rays would destroy most life on Earth. Gases in the atmosphere also hold in heat. The Earth's average temperatures would fall below the freezing point of water without atmospheric gases to hold enough heat. The balance between blocked radiation and radiation allowed to reach the Earth makes life possible..

2.

The Earth's atmosphere contains water. As water evaporates or is given off by living organisms (respiration in animals, transpiration in plants), it rises through the atmosphere and forms clouds. Wind moves the clouds over the surface of the planet. When the clouds condense into rain, snow or other forms of precipitation, the water falls on the surface of the Earth. In this way, the atmosphere regulates the balance of water on Earth and delivers precipitation to areas that otherwise would not have water.

3.

Life on Earth needs the atmosphere to breath. Animals take in breathable oxygen from the atmosphere and use it to metabolize food into energy. Plants use carbon dioxide to grow and sustain life. The balance between these two gases is important as well: animals need enough oxygen to breathe and plants need carbon dioxide, but too much carbon dioxide traps heat in the atmosphere, leading to global warming.

4) you never know it could be still sunny , cloudy , stormy..etc

5)

Water is recycled through the water cycle. It evaporates from the oceans, forms clouds, it rains (or snows), the rivers return the water to the ocean.

The longest timescale of water anywhere in the cycle is in the deep ocean (it stays there for several thousand years) and in deep ground water (perhaps 10,000 years).

However, water is very slowly destroyed chemically in photosynthesis (plants converting carbon dioxide and water to sugars and oxygen) and recovered again in respiration (basically the reverse of photosynthesis to make energy and CO2).

You can calculate how much water remains from the dinosaur age from the total amount of water on the planet and the amount of water taken up in photosynthesis per year.

The Earth's plants take up about 12,000 billion kg of water per year (we know that roughly from the CO2 they take up).

The total water on Earth is about 1400 billion billion kg. So within about 100 million years most of the water will have been chemically destroyed. Dinosaurs lived 65 million years ago.

So, SOME of the water we drink is the same water, but more than half is different water.

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

would be false hope this out
