Unit 4 Astronomy：the science of the stars地壳运动使地球分裂为七大洲，未来七大洲会继续分裂还是合为一体？Will the continents join again in the far future?In the beginning，more than 4.6 billion years ago，the world was a ball of burning gas，going round and round through space.At first，hot gases were able to escape into outer space，but as the earth cooled，they were held by gravity to form the early atmosphere.Clouds began to develop as water vapour collected in the air.And then it began to pour with rain，causing the early oceans to rise up.It took hundreds of millions of years for the first land masses to appear.About 250 million years ago，long，long after the earth had formed，all the continents of the time had joined together to form a supercontinent called Pangaea(盘古大陆)．This supercontinent broke up about 200 million years ago to form two giant(巨大的)continents，Gondwana and Laurasia.Gondwana was made up of what is now Africa，South America，Australia，Antarctica and India.The Indian subcontinent lay off the east coast of Africa，before it broke off and moved north rapidly.It collided(碰撞)with Asia，creating one of the world's greatest mountain ranges，which extends for more than 2，400 kilometers－the Himalayas.By now，our world had started to look like something we would recognize.The amazing process of plate tectonics (板块构造)，in which the earth's land masses move slowly across the earth's crust(外壳)，is still continuing.Far in the future，some scientists have predicted that the present continents will join again to form a new supercontinent.Only time will tell...阅读短文，判断正(T)误(F)1．The early oceans appeared because of the rain which developed from hot gases.( )2．Pangaea was made up of what is now Africa，South America，Australia，Antarcticaand India.
