What is the line called that get the hottest temperatures?

Whats the river course?
Journey the river takes from source to mouth
The 3 stages of volcanoes

Closest layer to earth
Troposphere
4 ways of river transport
Rolling, solution, bouncing, suspension
Landform that goes through Iceland
Differences in destructive and constructive waves
Destructive erodes the coastline as backwash is stronger, constructive deposits sediment on the coastline as swash is stronger
How do you give a grid reference? Example of one?
LEN
Why is the earth unevenly heated?
The equator gets direct sunlight rays, north and south get slanted sunlight rays
Give 2 reasons a river might deposit sediment/load?

2 positives and negatives of dams
Positive - reservoir supplies water. Reservoir used for water activities. Generates hydro electric power. Attracts wildlife.
negative - dams require relocation of families as land might be damaged. Land may get flooded. May damage wildlife, environment.

How does a lagoon form?
Longshore drift transports sediment/sand up the coast. If it comes across a bay, it may spread as a spit. If it goes across the whole bay it is a sand bar, separating water known as a lagoon.
