Explanation:

Statement 1st is correct: Isotherms  follows the parallels of Latitudes in an east west direction. There is a shift in the position of isotherms with the change of season. Where horizontal temperature changes are large, Isotherms are closely spaced. Where horizontal temperature differences are less, Isotherms are widely spaced. Due to differential heating of land and water, temperature above the oceans and land masses varies even on the same latitude. Isotherms, therefore, bend slightly while crossing from landmasses to oceans and vice versa.
Statement 2nd is correct: Coastal regions have a smaller range in temperature than continental interiors because their temperature is determined by the the temperature of sea water. Coastal regions have salty water therefore, water remains cool and when the cool breezes from water reaches the coastal regions, they become cool as well. Whereas continental interiors have bare land due to which they absorb more and more heat, therefore the temperature becomes hotter at continental interiors. Therefore, costal regions have smaller range of temperature than the continental interiors.
