Question

Activity N
° 1:
Read and circle the verbs in simple past.
The most accepted theory that explains the origin of the universe states
that it all started 14 billion years ago. Back then, there was
a tiny
particle, like an atom, which was very hot and dense. This particle
exploded causing the universe to form; matter started to expand and
created millions of galaxies. The galaxy we live in is called the Milky
Way
Our planet is approximately
4.5 billion
(
4,567,000,000
) years old. Its
origin is still
a mystery today, but some theories exist. ⊹ The “Core Accron Theory” states that at the beginning, our solar system
was rotating dust and gases. Then, the primitive sun’s gravity attracted
these materials and they all started spinning around it. Some clouds
formed and became solids. Our planet was formed by
a solid metal core,
a liquid mantle and
a thin but hard crust.
