Write a description of how a diagram can you solve 2 x 40

2 × 40

To solve it with the help of Diagram,

Draw a Rectangle having 8 rows and 5 columns. Draw a copy of this rectangle .You can draw rectangles of other dimension like (10 × 4 or 4×10, 5×8).

So, there will be total of 2 identical rectangles.

Each part of a rectangle = 1 object

So, there are 80 parts in all.

So , 2 × 40 = 80  

equal to

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
