Decreases

Which astronomer discovered that objects in space have an elliptical

orbit?

of Earth’s surface

What two forces help to keep

objects like the Earth in orbit

around the sun?

Gravity and Inertia

What type of Breeze is this?

Sea Breeze

What causes a Sea Breeze?

Daytime – cooler air moves from sea to replace warmer air on

land

2 Pointer!!!

What causes land and sea

breezes?
