Mesozoic Era is the second of the Earth's major era geologically of the Phanerozoic time. It means middle life in Greek. The climate during this time was warm and had less difference in the temperature today thus the answer is a. About as warm as present.

Answer 2

c. warmer than present

Step-by-step explanation:

The Mesozoic Era (Meso = Middle and Zoic = Life) is marked by the emergence of dinosaurs and encompasses the period from approximately 250 to 65 million years ago. It is divided into three periods, from oldest to most recent: Triassic, Jurassic and Cretaceous. This era was warmer than the present.

Its onset is marked by a large mass extinction of unknown causes and the formation and fragmentation of Pangeia. The enhancement and extinction of dinosaurs is also a striking fact of this era called the “age of dinosaurs” because that was when they developed most. It is also in this Era that the first flowering plants and the first birds appear.
