4. Stone tools were used to cut meat and bone, scrape bark(from trees) andhides(animal skins) chop fruits, roots and wood

5. Factory sites-places where stone was found and where people made tools6. Archaeologists have named the various ages as follows:

(a)Palaeolithic age-earliest period -2 million years ago to 12000 years ago-(Palaeo-old, lithos-stone). This is the longest period and is divided into lower, middle and

upper palaeolithic.

(b)Mesolithic age (middle stone age)-12000 years ago to 10000 years ago- stonetools were tiny called microliths

(c)Neolithic age- from 10000 years ago7. Ostriches were found in India during Palaeolithic age8. Paintings were done inside caves- colours were got from minerals

LESSON 3

export

19.Around 3900 years ago people stopped living in these cities20.New cities emerged about 1400 years later21.Egypt dry desert built huge tombs called pyramids- preserved dead kings in

them with food, ornaments and servants called them mummies the most

elaborate burials in world history

Lesson 3 (geo)

1. Rotation movement of earth on its axis-24 hours

2. Revolution-movement of earth around sun-365 days and 6 hours

3. The 6 hours added up and it becomes 1 day extra (in February) once in 4 years

called leap year
