During a total lunar eclipse, during totality, you'd expect:.
alexandr1967 [171]

I was a bit lost in the wording but I think I understand now...

When the lunar eclipse is in action, the earth's umbra thing will start covering the moon, making it possible to see it. When the earth's umbra completely covers the moon it will either have a red, brown or even sometimes a yellow look to it.

I think this was correct but I'm not sure about that. If this was wrong I'm really sorry and hope someone can give you the right answer for this.

Describe four expected impacts of global warming.
yawa3891 [41]

Many impacts can be  brought by global warming, here I would introduce two impact each on the aspect on ecosystem and agriculture.

On ecosystem:

1. Shift in distribution of plants:

The changes in climate brought by global warming will alter the natural distribution limits for vegetation. For example, forests are moving north into the ;and that was once Arctic tundra, while the growing season increased in northern high latitudes.

2. Extinction or endangerment of species

Species may not be able to cope with climate change unlike human, hence intolerance of the increasing temperature may led to the extinction of spices. For example, coral reef cannot survive under temperature over 30 degree Celsius hence facing the danger of extinction.

On agriculture:

3.Farm production lowered

A warmer climate would lead to a loss of soil moisture hence increasing the erosion rate, and the dry soil will lower the land productivity as crops cannot grow on these barren land, especially water thirsty crops such as rice.

4.Farm production destroyed

Pests may become more active given the shorter and warmer winter, while floods may be present more often given the rapidly rising sea level and the instability of the climate.

Hope it helps!

4. Explain the different forms of precipitation?
ruslelena [56]

Answer:

The most common types of precipitation are rain, hail, and snow.

Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface.

They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
