Answer 1

The cretaceous-tertiary mass extinction was apparently caused by a meteorite that struck Yucatan Peninsule in Mexico

Answer 2

The "cretaceous-tertiary" mass extinction was apparently caused by a "meteorite" that struck the Yucatan Peninsula.

Step-by-step explanation:

• The Yucatan Peninsula lies between the present-day 'Gulf of Mexico' and the 'Carribean Sea'.

• The meteorite that struck this peninsula about '66' million years ago was '10 to 15 kilometers' wide in size.

• A huge crater was formed after the meteorite hit the Earth at the Yucatan Peninsula. This crater in today's date is known as the "Chicxulub impact crater".
