records of precipitation on the coast of Peru

satellite records of cloud data

records of precipitation in high Andean villages

ocean surface temperature data from the tropical Pacific

On the Yucatan Peninsula in Mexico, scientists have been able to learn about the climate that affected the Mayans by:

examining written records of rainfall recorded in pyramids

examining sediments at Mayan archeological sites

examining changes in sediments along Yucatan beaches

examining sediments from the bottom of a regional lake

On the Yucatan Peninsula, what makes the lakes of Punta Laguna and Chichancanab ideal for gathering sediments?

They have a high sedimentation rates

There are few streams or rivers transporting sediment away from the lakes

The water is rarely disturbed in these lakes

All of the above.
